• Take a multiple snapshot of different VM´s

  Hello

  Anyone got a script to take different VM´s. example multiple snapshots when you windows patch id like to snapshot slected vm´s before applying the patch.

  Christer S

  Hi Chrsun02,

  "is it a medium esay to ad a function report to the commnad.

  Please tell more that you want to report on

  "im"wishing to' an easy way to get rid of stereotypes when I know that servers is ok. "

  Right, so before patching, you created snapshots for some virtual machines, and gave you the name of the snapshot for this purpose.

  for example

  Get - vm testgk | New-cliché - memory: $false - suspend: $false-name "testsnapshot001" - Description "my snapshot test patch before.

  on my vm testgk, I created the new snapshot with the name "testsnapshot001" for this pupose

  now I want to remove it

  Get - vm testgk | Get-Snapshot? {$_. Name - eq "testsnapshot001"} | Remove-Snapshot

  So I have vm testgk query, ask this virtual machine snapshots that have name testsnapshot001, and then delete the snapshot.

  If you have created snpahosts for more virtual machines give their name separated by a ",".

  Get - vm "vm1', 'vm2', 'vm3 | Get-Snapshot? {$_. Name - eq "testsnapshot001"} | Remove-Snapshot

  If you're sure you didn't any what other snapshots you can omit this part?: {$_. Name - eq "testsnapshot001"}

  so in the end, you would write:

  Get - vm "vm1', 'vm2', 'vm3 | Get-Snapshot | Remove-Snapshot

  If you don't want to answer the question confirmation add - confirm: $true

  Get - vm "vm1', 'vm2', 'vm3 | Get-Snapshot | Remove-Snapshot - confirm: $true

  If you want to specify vms not with names but with location:

  Get-cluster "my_cluster01" | get - vm | Get-Snapshot | Remove-Snapshot - confirm: $true

  If you want to get a report for snapshots:

  Get - vm | Get-Snapshot? {$_.name - eq "testsnapshot001"} | Select the name of name,@{N='VM'; {E = {$_.vm}}, @{N = "CreatedOn"; E={$_. Created}}

  So it will go through all of the virtual machines, instant advertising with the name: testsnapshot001 and display its name, date, name of the virtual machine

  Get - vm | Get-Snapshot? {$_.name - eq "testsnapshot001"} | Select the name of name,@{N='VM'; {E = {$_.vm}}, @{N = "CreatedOn"; E={$_. Created}}

  VM name CreatedOn name
  ----                                         -------                                 ---------
  testsnapshot001 testgk 21/08/2012 14:09:47

  And even once on the line will interview all machines virtual registerd in vc. If you want to check only for some more specific:

  Get - vm "vm1', 'vm2', 'vm3 | Get-Snapshot? {$_.name - eq "testsnapshot001"} | Select the name of name,@{N='VM'; {E = {$_.vm}}, @{N = "CreatedOn"; E={$_. Created}}

  or

  Get - vm "vm1', 'vm2', 'vm3 | Get-Snapshot | Select the name of name,@{N='VM'; {E = {$_.vm}}, @{N = "CreatedOn"; E={$_. Created}}

  to query all snapshots there and not only those that have been made for the purposes of the application of patches

  OR!

  a dirty, quick control for VMS with snapshots in general:

  Notice-EEG - ViewType VirtualMachine-filter @{"snapshot" = ""} | Select name

  I would like to know if it works for you.

  Kind regards

• Small Noob Question - multiple snapshots

  VMware Server 2 using the Web interface to manage my VMs, I see the following commands under the snapshot:

  Take a snapshot

  Go back to the snapshot

  Remove the snapshot

  I took several shots.  but when choosing to go back to the snapshot, it is only up to the last snapshot.  Also withdrawal snapshot deletes the last snapshot.  Is it not possible to have multiple snapshots in this version of VMWare? TIA!

  VMware Server 1 and 2 have only the ability to 1 snapshot.  (A limitation of design from the beginning.)  If you need multiple snapshots, you must change for ESX (i) or workstation (or merge if you have a Mac).

• Multiple snapshots

  Someone remind me how best to do so. I found a virtual machine that has 6 shots dating back to November. We want to keep any changes.

  I have to go back and committed each of them in the order (oldest to newest?) Or just hire the newest one?

  Just a little backwards, but that's ok.  So if you take five snapshots n them sequentially over a period of five days and you wanted to commit to the current state of the machine you would remove 5, then 4, then 3, then 2 and finally 1.  I know it seems backwards, but it's the way that you are able to turn back the clock, if you wanted to snapshot 3 and validate these changes if you want to.

  If you really want to learn how to work the snapshots create a test computer and create some shots and some branching off to.  Open Notepad and create different documents allowing them to save money, but also leave them open for the screenshot displays on the thumbnail on each of them.

• Trying to hot-clone VM with multiple snapshots

  I have a virtual machine with two snapshots.  I need to make a clone of this virtual machine, and I want to clone the current state-based, not off a previous snapshot or the basic disk.

  When I try to clone, compatility validation is to give the warning "returning to snapshot may generate error (warnings) on the destination host."

  I'm curious to know what, if anything, will break if I continue with the clone?  I would like once again, the VM cloned to be based on the latest state of the virtual machine, not on a snapshot or the basic disk?  I thought that was possible?

  Thank you!

  The reason for the error is that when you clone to another ESX host a snapshot (especially if it includes memory) may not work on the new host because it is based on the current hardware that is running the virtual machine (at the time the snapshot is taken) maybe not on that get back you to the snapshot on. Also all the files that make up the snapshot are not available on the destination virtual machine.

  The best way is to simply validate snapshots and then do it. If this is not possible just clone and it will be based on the virtual machine running and you will have no problem.

• Question about Equallogic snapshots.

  Hello forum

  I could not confirm this, but instant never need to commit anything to the basic volume?

  Lets say I have 10 snapshots and delete the oldest? There will be a load of e/s to validate these instant changes?

  Also, if someone could point me to any type of indepth explanation of this technique of snapshot, I would be interested to read all that.

  Thank you!

  N ° current data are already on the base volume.  There is nothing to commit.   Only if you are completely restoring a volume from a snapshot will be there in writing for the base volume.

  On the site of Equallogic Support KB:

  Solution title TABLE: how the snapshot reserve space is allocated and used

  Solution details Snapshot Reserve Allocation and use

  -------------------------------------

  In a series group PS, snapshots can protect against errors, of a volume

  virus or the database. A cliché represents the content of a volume

  at the time you created the snapshot. Creating a snapshot does not disturb

  access to the volume, and the snapshot is instantly available allowed

  iSCSI initiators.

  Before you can create snapshots for a volume, you must allocate space (called

  snapshot pool) for snapshots. You set the value of the snapshot reserve

  When you create or modify a volume. Snapshot reserve benefits from the same

  as the volume of the pool data.

  When snapshot data consume entire supply snapshot, the Group remove is

  the oldest snapshots to free up space for new images or sets the volume and

  snapshots offline, according to the policy you selected for instant recovery

  space.

  The functionality for creating snapshots is called hybrid allocate when writing.

  Operation of sharing and snapshot of the page

  -----------------------------------

  A PS Series Group organizes the physical storage into logical segments called pages.

  Each page is composed of several logical blocks. This is similar to the way file

  systems combine areas of physical disk in 'clusters' or 'chunks '. Each page has

  a reference count which records the number of volumes and snapshots that share

  the page.

  When you create a volume, the group creates an internal table, called the volume

  table, which contains pointers to pages that use the volume. When you create

  a snapshot of a volume, the group creates a snapshot table by making a copy of

  the volume table, which is usually an operation in memory that the Group

  run in a transactional manner. For each page of volume in use, the support group increases the

  reference count to indicate that the volume and the snapshot share page.

  Because the group does not move or copy the data or allocates a new pages, photos

  are fast and efficient.

  Reserve of the snapshot stores the differences between the data on the volume and snapshot data

  (in addition to differences between the data of multiple snapshots). When you

  first create a snapshot, the page for the volume and the snapshot tables are

  In brief identical copies and the snapshot consumes no snapshot

  reserve. A reading of the same logical block of the volume application or the

  snapshot returns the same data because the application is reading from the same page.

  However, if you write a page that has a volume and a snapshot of share, snapshot

  reserve is consumed.

  Here's a simplified example of a snapshot operation. In general, no.

  additional I/o operations are needed to manage the data volume or snapshot.

  However, other internal operations can occur due to virtualization and

  data balancing on berries of the PS Series.

  If an application performs a write to 8 KB for a volume containing a snapshot, the

  Group:

  1. determine what page is modified by the write operation.

  2 - If the page is not shared, writes the data to the page.

  3. If the page is shared:

  . (a) allocates a new page of disk space and reduces the instant to reserve

  . the volume of a single page.

  . (b) update the page of volume table to point to the newly allocated page.

  . (c) mark the newly allocated page as having new data on the volume and the references of the

  . original page for unchanged data.

  . (d) writes the data to the new page.

  When writing is complete, if you read the data on the volume, you have access to the

  new page and new data. However, if you read the same logical block of the

  Instant, you get the original data, because the snapshot will always point towards the

  original page. Similarly, if you set a snapshot online, write to the snapshot.

  feature hybrid write protects the original data volume by allocating

  a new page for the new snapshot data.

  Only the first page of writing to a volume shared (or snapshot) consumes additional

  snapshot reserve. Each subsequent entry is considered identical to a writing on a

  non-shared the page because the original data are already protected.

  Functionality similar to hybrid allocate when writing is used in cloning operations.

  However, unlike when you create a snapshot, cloning a volume immediately

  consumes space additional group. If a clone is moved to another pool, data

  is copied during the operation of moving pool.

  Restoring a Volume from a snapshot

  ----------------------------------

  Because of the layout table, restore a volume from a snapshot is very

  quick. First of all, the group automatically creates a snapshot of the volume by copying

  the volume table to a new table of snapshot. Then the Group transposes the page tables

  the volume and the snapshot you selected for the restore operation. NO.

  additional space is required, and no data is moved.

  Deletion of Volumes and Snapshots

  ------------------------------

  Because volumes and snapshots to share pages, if you delete a volume, you

  automatically remove all the clichés associated with the volume.

  You can manually delete snapshots (for example, if you need more of)

  snapshot data). In addition, the group can delete snapshots automatically in the

  following situations:

  1 - failure instant free reserve. If the snapshot data consume the snapshot

  . reserve, the group either deletes the oldest snapshots to free up space for new

  . snapshots or sets the volume and snapshots in offline mode, according to the policy

  . you have chosen for the snapshot space recovery.

  2 - maximum number of snapshots, created from an agreed timetable. If you set up a

  . timetable for the creation of snapshots, you can specify the maximum number of

  . photos you want to keep. Once the program creates the maximum number

  . clichés, the group will delete the oldest snapshot for planning

  . to create a new snapshot.

  Snapshot are deleted in the background queue. The group travels

  the snapshot page table and decremented the reference count on every shared page.

  Any page that has a zero reference count is released into free space. Pages

  with a zero reference count are not released because they are shared with

  the volume or other snapshots.

  Because stereotypes can be automatically deleted, if you want to keep the

  given to a snapshot, you can clone the snapshot.

  Reserve snapshots use agreement

  ------------------------------------

  The snapshot reserve is consumed only if you write a shared volume or snapshot

  page. However, it is difficult to establish a correlation between the amount of data written in one

  volume (or snapshot) with the amount of instant reserve consumed as a result.

  especially if you have multiple snapshots.

  Because the pages consist of several logical blocks, size e/s and distribution

  volume merge affect overall performance of e/s in addition to the snapshot

  reserve its use.

  For example, do much written about a narrow range of logical blocks in a volume

  consumes a relatively low amount of reserve of the snapshot. This is because as Scripture

  the same logic block more than once, does not require not additional snapshot

  reserve.

  However, doing random number wrote a range of logical blocks in a

  volume can consume a large amount of reserve of the snapshot, because many other

  pages are affected.

  In general, use instant reserve depends on the following:

  1. number of entries that occur in the volume (or snapshot) and at least one

  . snapshot exists. In general, more Scriptures tend to use more snapshot reserve.

  . Although multiple writes to the same logical block do not require additional

  . space.

  2 - the range of logical blocks, on which occur the Scriptures. Written in a wide range of

  . logical blocks tend to use more instant reserve written in a narrow

  . rank, because more of the written word are to different pages.

  3. number of snapshots of the volume and timing of the write operations. Most

  . snapshots that you create more snapshot reserve is necessary, unless there is

  . few entries on the volume or snapshots.

  4 - age of snapshot. Snapshots older tend to consume more snapshot reserve only

  . the clichés of recent because the group must retain the original data for a

  . longer time.

  Design Snapshot reserve

  -----------------------

  You cannot create snapshots until you book instant space. Snapshot reserve

  is set as a percentage of the reserve volume (space) for the

  volume.

  When you create a volume, by default, the volume uses instant group-wide

  reserve adjustment. (The reserve in the scale default setting is 100%. You

  can change this default value.) You can change the reserve snapshot setting when you

  create a volume or later, even if the volume is in use.

  Although the snapshot reserve is not used until the volume or writing snapshot occur, it

  is consumed immediately free pool space. For example, if you create a

  fully allocated (not thin provisioned) 200 GB volume and specify a snapshot of 50%

  pool of reserve, free space is immediately reduced to 300 GB (200 GB for the volume

  reserve and 100 GB for Snap reserve), even if there are no pages in use.

  Therefore, before you create a volume, you should consider how many snapshot

  reserves, if any, to assign to the volume. The reserve of the snapshot set to zero (0)

  If you do not want to create snapshots.

  The optimal size of the snapshot reserve depends on the amount and type of

  changes in the volume and the number of shots you want to keep.

  By example, if you set the snapshot reserve 100%, and then create a snapshot.

  You can write to each byte of the volume without missing snapshot

  reserve. However, if you create another snapshot and then write in each byte of

  the volume, the first snapshot is deleted in disk space available for the new snapshot. If

  you set the instant reserve at 200%, there would be a sufficient reserve of snapshot

  for the two snapshots.

  A very conservative strategy in terms of instant reserve sizing is to put the snapshot

  book value at 100 times the number of shots you want to keep. This

  guarantees that keep you at least the number of snapshots, regardless of the

  the number of entries on the volume. However, this strategy is generally allocates

  book an excessive amount of snapshot, because that rarely crush you all the

  the data in a volume during the lifetime of a snapshot.

  The best way to instant size reserves is to assign an initial value to the reserve

  and watch how instant you can keep over a period of time specified under a

  normal workload. If you use tables to create snapshots, allow the

  calendar of work for several days.

  To get an initial value for a snapshot reserve volume, you must estimate

  the quantity and the type of entries in volume and the number of snapshots, you want

  keep. For example:

  -If you wait a few Scriptures or writings which are concentrated in a narrow range

  . logical blocks and you want to keep only a few shots, start with a value

  . 30%.

  -If you wait several entries or entries that are random in a wide range of

  . logical blocks and you want to keep more than a few shots, start with a value

  . 100%.

  If the snapshots are deleted until you reach the desired number of snapshots,

  increase the percentage of snapshot reserve. If you reach the desired number

  shots without consuming much of the instant free reserve, decrease the

  percentage of reserve snapshot. Continue to follow instant reserve and

  adjustments as needed.

  How Thin Provisioning button Snapshot Reserve

  ----------------------------------------------

  The snapshot reserve is based on a percentage of volume reserve (allocated space

  a volume). For a volume fully provisioned, the reserve volume is equal to the

  stated volume size. However, a thin volume put into service, the volume of reserve

  is initially very inferior to the reported size (default is subject to minimum volume

  10% of the reported size) and increases as the written volume occur.

  If you change a thin volume supplied in a volume fully provisioned, the

  amount of reserved snapshot increases automatically, because the volume of reserve

  increase in the size of the stated volume.

  If you change a volume of fully provisioned to thin-provisioned, the amount of

  snapshot of reserve decreases automatically, because the volume of reserve declines.

  However, if the snapshot resulting reserves will be too small to store all the

  existing snapshots, the group will automatically increase the instant reserve

  percentage of value that preserves all existing snapshots.

  Reducing the use of instant reserve

  -------------------------------

  Over time, you can reduce the use of instant reserve by periodically (for example,

  Once a month) defragmentation of databases and file systems. Defrag operations

  try to consolidate segments of files in a volume and, consequently, to reduce the scope

  logical blocks addresses used in the pages of the volume.

  Defragment the data read operations from one place and then write data to a new

  location. So increased use of instant reserve during and immediately

  after defragmentation, because existing snapshots will use more of the usual

  amount of the snapshot reserve. However, snapshots created after defragmentation

  operation must use less instant reserve, because the data on the volume are more contiguous.

  When a volume is highly fragmented, potential reduction of the snapshot reserve

  use can be dramatic, especially after removing the large before you defragment

  snapshots. Defrag operations can also reduce the I/O load on the group,

  because the contiguous data makes more efficient i/o operations, in order to improve the

  e/s overall performance.

  Latest defragmenters are good to reduce the fragmentation that is not seeking to be

  too thorough. Some defragmenters also try to combine the inactive data

  further restricting the likelihood of changes to shared pages. However, are not

  Defragment too frequently.

  Sector alignment may also affect the use of snapshot of the space, especially in

  larger volumes. File systems must be correctly aligned with the sector. It comes

  described in technical reports for VMware and Windows environments.
