CX3-20: host in several storage groups?

Similar Questions

• Storage groups

  Hello

  At the start of SAN in UCS, what is the best practice when creating the storage groups in the drive Bay?

  For example, VMware: is it best practice to have a storage group for each ESXi and add its own ESXi Boot LUN (id = 0) and the necessary VM LUN data store?

  Other environments (Linnux, Windows, Hyoer-V) have something special in these terms to support?

  Thank you

  It's a security issue.  Because the LUN ID can be changed easily on the host computer, you could continuously clobber the LUN hurt if your server administrator has incorrectly changed LUN ID.  In addition, once a host is started, it will be able to see & access each LUNS in the storage group independently LUN ID.  The importance of the impacts host LUN ID matches only a host trying to start SAN.

  The two main forms of security applied to the storage is zoning and masking.

  Zoning - on storage switch, acts as an ACL restricting the scope of what can see the members of the zone.  An area will normally contain only a single host and target WWN.  * Who I can see *.

  Masking - on the table limits of storage 'what' LUN a host has access to.  This is done in the form of storage groups.  * What can I access *.

  Either work around poses a great risk to corruption or destruction of data given that different operating systems can be read their native file systems.  E.g. If you had all your hosts in a storage group (ESX, Windows etc.) and tried to separate them only by a LUN ID, a simple change of 1 digit of the start ID LUN on the initiator target could lead a crowd to not read the file system and potentially right a new signature to the risk - replace your existing data.  Windows cannot read a linux partition and vice versa.

  Follow these best practices and your data will be much more safe & secure.

• Orientation of storage group

  Hi all

  We are expanding our storage environment and wanted some advice on setting up our group/pools.

  We currently consisting of 12 TB PS4000E storage group, it is used as mass storage for files and archiving of mail servers. All volumes are in the default storage pool.

  We bought a 24 CT PS4100E and a 14 TB PS6100X to add to this group. The idea is to migrate existing data from Vault/e-mail on the server of the PS4000E file, so it can be removed from the Group and used elsewhere in the company.

  In scenario 1 we add two devices in the Group and separate storage pools and migrating volumes from the storage pool by default for the pool containing the PS4100E. Then remove the PS4000E of the group.

  In scenario 2 we have the PS4100E and the PS6100X in the same pool of storage and migrate the data in the same way. The group can then distribute the data as seems it.

  In the future we will migrate VM storage over another group, containing a PS5000.

  What are the considerations of raid level and pool for these scenarios? RAID5 has been recommended for both of the new features, but can they coexist in the same pool and work well with the same level of raid?

  Thanks in advance.

  Jim

  Yes, you can run different RAID levels in the same pool and through different speeds with him when to use the latest version of the firmware (5.x and v6.x).

  You can add new members in any combination you like (an a R10 two R10 or the two R6, or alone as a R6).  APLB (Automatic Performance Load Balancing) will examine various aspects of i/o, disk speed, type, RAID and determine the best placement for the slices of volume and move the data according to the needs (in the background) to provide the best performance.

  Just note that because the SAS bays generally have more space, volumes have generally several sections on the largest capacity table.

• Unit - mailbox moved to the new storage group is not available

  Hello

  I have a 4.0 (4) unit UM with a message from Exchange 2003 offbox store. During the initial installation, only the first storage group on the mail server was present and mailboxes of the users are hosted here.

  Recently, a new storage group was created on the mail server and a mailbox has been moved from the first group of storage to the new storage group. The Subscriber is able to receive voice messages via e-mail, however his MWI does not illuminate. When it tries to connect to retrieve messages on his phone, the unit said "your messages are not available now.

  I am able to create or import users that are hosted in the new storage group, but I'm having the same symptoms. Is it necessary to rerun the configuration of message store wizard?

  Thanks in advance.

  Have you run Assistant permission for the new Bank of mailboxes?

  The other thing to do is to restart the AvMsgStoreMonitor service; But wait after hours. A reboot will do the same.

• Replication storage group

  Just a quick question about automated replication.

  I noticed that, sometimes, a stack of app will be automatically repeated at all storage in a storage group, as soon as the stack is created. Maybe it's just a coincidence of timing. Other times, I have to use the button repeated in storage group menu, which I am reluctant to do it because I guess, he is everything that the replication (in the case where there may be changes).

  Is there a timetable? Can I force replication just to a single appstack, for example by using a command line on the server?

  Just for reference, we use only local flash storage on the hosts for the non-persistent linked clones, so we need to replicate to all the machines see the battery.

  the timing is every 4 hours and no its not configurable. You can force replication, but not for a single AppStack. However if there is that one added and you force a replication, it will only replicate a new a

• LOW 5.0 API search Exchange storage group

  I had a problem to find the location of the storage group Exchange (2003 environment) within the API 5.0.  I have no problem to find the name of the actual exchange server however I do not know which class contains the value real homemdb (if any.)

  Any help is appreciated,

  Thank you

  Rob

  Hi Rob,

  The BES does not connect to any Exchange database so that there is no API to return this value. All communication is done via MAPI.

  A good rule of thumb, if something is not possible to be found/made using the console BOTTOM it is not supported in the BAA.

• How to work on the strategy of Distribution of the storage group?

  Any body can help me to understand the strategy of Distribution of the storage group?

  The App, the storage Volumes have the option below:

  Spread: Distribute files in all storage locations.
  When a file is created, the storage with the most available space is selected.

  Round-robin: Distribute files sequentially using the storage locations.
  When a file is created, with the oldest time used storage is selected.

  I don't know what is different from this two option. When I select this option, I can see on my environment? Thank you.

  I think that it is used only for writable volumes right?

  If you are using storage with appstacks groups all appstacks are synchronized between the two storage when you use the sync option.

  When you create writeable volumes in the storage group it will create in one of the stores of data defined in the storage group.

  Let's say your staorage is called ST1, ST2, ST3 and ST4 and ST1 and 2 are 100GB and 3 and 4 are 1000GO then that's what happens.

  East Round Robin

  ST1, ST2, ST3, ST4, ST1, ST2, ST3, ST4 and so on and so forth. It would take into space wanted account.

  With the other he will do

  ST3, ST4, ST3, ST4, until both have also 100 GB of disk space and it will then be evenly.

• Volume App storage groups

  Has someone already implemented App Volumes storage groups?

  I've set up a group of storage with the following parameters:

  • Automation: "Appstacks of auto import" and "Automatic Appstacks replicate" active
  • Distribution strategy: left by default to "spread" that this only applies to writable volumes according to the documentation and I don't use the accessible volumes in writing
  • Storage of model: I chose here the LUN where my appstacks
  • Selection of storage: Direct
  • Storage: I chose here the LUN I want my appstacks to replicate to

  but nothing seems to happen.

  I'm doing something wrong?

  Looks like you selected only 1 storage location. You must select 1 more data store for replication to occur. Typically, you would select the data store that you create the appstacks on (the same data store that you used for the storage of model) and data 1 or more additional warehouses to replicate. So, using the direct selection of storage, you must have a minimum of 2 warehouses of verified data.

• Data warehouses do not appear on all of the hosts even though storage devices appear on all hosts

  I have a frustrating problem that I can't solve, my data stores do not appear on all of the hosts even though storage devices appear on all hosts.  Tips on troubleshooting this would be greatly appreciated, it is connected to a Synology NAS iSCSI environment and I use it for my VCAP studies right now, or was

  Tried a lot of things so far...

  -Recreate the target and starting from scratch

  -recreate the cluster from scratch

  -Restart the storage

  -Restart the hosts (I think that I did in all cases)

  
  

  And probably a few other things, would appreciate any other advice/lessons

• Adding a lun to multiple storage groups

  Is it OK to have the same LUNS in storage groups? I'll put up a new cluster and its own storage group. But I need to have other LUN mounted in the other cluster so that I can migrate virtual machines to this new cluster

  Fix. It's all basically just of masking.

• Max or recommended LUNS per storage group

  I can't find any definitive or maximum recommendation for the number of logical units (VMFS5), which can be placed in a storage group.

  Can someone point me to some documents that indicate this and possiblly some explanation of ups and downs?

  32 data warehouses by cluster of data by the maximum configuration store.

• How to reach esxi host 5 on storage area network

  I have a Dell PS6000E on my network.  I would like to create a volume on it and use it as a shared storage for a new configuration of esxi5 with 2 hosts.  The PS6000 already contains 2 volumes in use by other servers (physical).  To access the PS6000 via my regular local network hosts.  Is this possible, and is there a documentation on how to put in place?

  Thank you

  Welcome to the community - I guess you access the PS6000E are configured for iSCSI or NAS/NFS, you will be able to access as shared storage long ESXi hosts can reach the unit. Because ESXi hosts will not be able to share the LUNS in use by other servers, you're going to create a new LUN for ESXi hosts. This storage of ESXi - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-storage-guide.pdf - guide that has information on how to configure your ESXi servers to access the storage.

• Upgrade of a single host with Shared Storage

  Getting ready to upgrade my ESX 3.5 hosts to vSphere.  I've already upgraded to vCenter.  I have two hosts managed by vSphere, and both hosts have a storage area of channel shared fiber that guests are on.  Each server can see all shared data stores.  I want to upgrade a single host first, then later upgrade the other host.  I've migrated the guests running to 2nd host whose I am not upgraded at the moment.

  My question is can I upgrade the first host using Update Manager?  What happens to guests in data warehouses that run on 2nd hosts?  Will they be affected?

  > My question is can I upgrade the first host using Update Manager?

  Yes.

  > What will happen to customers in data stores that run on 2nd hosts? Will they be affected?

  They will not be affected.

• Cisco ACS 4.2 a user in several local groups

  Currently, I like this group map

  ACS groups window

  GRP of GRP-A-B-1 and PDM - 2
  GRP - A. GRP - 1

  GRP - Grp-2 B

  For example currently a user test1 is part of two groups 1 and 2 under windows and is mapped to the Grp-A-B of the CSA. Is it possible if I delete the mapping of Grp-A-B in ACS and can see the user test1 speratley in both groups (Grp - A and Grp - B) to GBA?

  Salam Muhammad,

  If you have a local user in ACS, this user cannot be a member of both groups at the same time.

  The same concept applies to external users. They cannot be mapped to two different groups at the same time.

  If you delete the configuration of Grp-A-B, the test1 user will be mapped to the first group in the list because ACS 4.2 process mapping group in the order:

  ' the snip "'

  Order of group mapping

  ACS always maps users to a single group of TISA. However, a user can belong to several groups the group mapping. For example, a user named John could be a member of the ensemble of the engineering group and California, and at the same time be a member of the combination of Group Engineering and management. If the value of group ACS mappings exist for these two combinations, ACS must determine what group John should be affected.

  ACS prevents contradictory group set mappings by assigning an order of mapping for the whole group maps. When a user who is authenticated by an external user database is assigned to a group of ACS, ACS begins at the top of the list of groups for this database mappings. ACS sequentially checks group memberships of user in the database of the external user against each group mapping in the list. Where to find the first set group mapping corresponding memberships to external users in the user database, ACS assigns the user to the group this group map ACS and ends the process of mapping.

• Configure a cluster of vsphere with 2 host with internal storage shared via HP LeftHand - doubts

  Hi, I'm trying to create a two-node esxi cluster. These nodes will share their internal storage with HP Lefthand Appliance (HP StoreVirtual VSA). I need the first steps to create the cluster, or better, the macro blocks, IE:

  -install esxi on each node
  -install Virtual Center and create the vmware cluster

  -Deploy the VM VSA...

  I have a lot of doubts because of the reason why I can't have (installation of the HP guide said) virtual machines on other than the VM VSA itself VSA data store. How can I configure things? Creating first two warehouses of data, deploy VCenter on a data store, create the cluster, deploy VSA VM on the other data store...

  Can you help me please?

  DL380G5 host as the location for the ODM is ok, but you may need to upgrade the host in any case since v12 FOM requires ESXi 5.0 or newer.

  ... what happens if the update fails and the hypervisor does not start more?

  I know we can't answer a question with a question. Anyway, how do save you virtual machines on this host now?

  It is true that the VSA VM cannot be migrated, but I can migrate the VCenter to a to another data store when I will have created the DATA of VSA data store (one that the hypervisor consider as an iSCSI target), I'm good?

  I'm sure that it is correct. Unless I'm missing something, vCenter Server is just another virtual machine running on the cluster VSA VSA does not require vCenter Server to run.
