How to calculate the space needed to move a member to another pool?

Dear,

We move - Member3 - member to a pool of maintenance for the upgrade of the firmware.

My question is how can we calculate the space needed to move a member to another pool?

I have attached some pictures of SANHQ for the pool/ability/member of the group.

PS To consider space group not the pool area, because we have a fourth demo maintenance pool member and we it will move to the default pool for the process of upgrade only.

Kind regards

Turki

Try this:

Re: cancel the mapping.  Some points to remember.  Cancel the MAPPING does not work on the replicated volumes, it's either sync replication or point-in-time standard.   Also according to the file system, it will not immediately reclaim the unused space on existing volumes.   Some file systems like VMware VMFS does not cancel the map on the fly, but offer a CLI utility to create large balloon files then delete and send him UNMAP commands simultaneously.

The basic rule is that you must have enough space to move the member selected out of the pool.   If this isn't the case, then the operation will not be allowed.  You may end up having to add the new Member to the pool until you can move a table.

Note: If you do not already done, then the site of Equallogic, with FW downloads is a document that describes how to set the value of disktimeout for several OS.   This allows the host (or the guest virtual machines) to cross the short breakdown during a firmware update or a failover of controllers due to a failure of the CM.

Kind regards

  • How to calculate the polynomial graphic adjustment of waveform

    Hi all

    I am new to lab - view so would need a little assistance in one of the problem I have right now.

    My problem is: how to calculate the polynomial graph of waveform data adjustment? I need to convert the waveform to XY graph data, and then use the polynomial vi made integrated to calculate the fitting?

    Detail: My problem is that I have waveform graph, I calculate the vertices and the Valley, but because of the noise, my peaks and Valley detection is sometimes not exact, so to smooth the chart that I must apply the polynomial fit.

    If anyone can help me in this, I'll be very grateful.

  • How to calculate the CPU Ready on Cluster DRS via Powercli?

    Hi all!

    I have a DRS Vsphere cluster. I want to know what is the value of the loan of CPU I have in my group.

    For example, I get 20% of powercli value, it is normal for the cluster, but if I have 100% or more, I have a problem.

    How to achieve via Powercli? And how to calculate the percentage values correctly?

    I know, I can get all values of CPU Ready of VMs cluster, but IT is not the same thing, I need overall value of CPU Ready.

    Thanks in advance!

    As far as I know you can get the cpu.ready.summation for ESXi nodes or VMs.

    For a cluster, you will need to get the value of each node in the cluster ESXi and then take the average.

    The metric cpu.radey.summation is expressed in milliseconds.

    To get a percentage, you need to calculate the percentage of loan period during the interval during which it was measured.

    Something like this (this will give the loan current %)

    $clusterName = "mycluster.

    $stat = "cpu.ready.summation".

    $esx = get-Cluster-name $clusterName | Get-VMHost

    $stats = get-Stat-entity $esx - Stat $stat - Realtime - MaxSamples 1 - forum «»

    $readyAvg = $stats | Measure-object-property - average value. Select - ExpandProperty average

    $readyPerc = $readyAvg / ($stats [0].) IntervalSecs * 1000)

    Write-Output "Cluster $($clusterName) - CPU % loan $(' {0:p}'-f $readyPerc).

  • How to calculate the sum of two digital form fields based on the selection of the checkbox.

    I have a form in Acrobat Pro who needs a custom calculation. How to calculate the sum of two digital form fields based on a selection of the checkbox. I have three number fields. Field-A and B are simple one or two digits. Field-C is the sum, or the total field. I want to field-C have a control box which, when turned on and off, just gives a. gives the sum of A + B

    _ Field - 2

    Thank you

    The custom field C calculation script could be:

        var v1 = +getField("A").value;
        var v2 = +getField("B").value;

        } else {

        }
    
    })();
    

    Replace 'A', 'B', and 'CB' with the real names of the fields.

    Try this - http://www.pythian.com/news/29703/oracle-instance-memory-usage/ for each of your instances.

    As far as I know, different instances may share only the binary code oracle and using libraries, so you should be able to easily understand the amount of memory of all instances of 12.

  • How to calculate the time to SELECT

    I want to know how to calculate the time taken by the SELECT query.

    For example: I run a select statement in TOAD (oracle version 9i) who takes 40 seconds to run, but in the output window, it displays few records. It says "list 1 of 500 records, more records exist". This table has total 20 million records.

    Now my question is: have you my SELECT query took 40 seconds? or it took 40 seconds to SELECT 500 records.

    If it took 40 seconds to SELECT 500 records then how to calculate the total amount?

    Any help would be much appreciated.

    To avoid the exit which is probably not really need you can make

    begin
      for c in (select * from xy /*your query */)
      loop
        null;
      end loop;
    end;
    /
    

    This gives an estimate of the time to recover all the lines.

    So, for example, the length of my video is 1070 seconds.

    But I want to be able to convert a format such as ' 00 (hours): 00 (mins): 00 (dry) ", '1070 seconds' how can I get this?

    What version of oracle?
    Install the OCR + VOTE in gross unit better than OCFS2. If you use 10g to 11 GR 1 material.

    If use 11 GR 2, take the OCR + VOTE in ASM disk group.

    You can check what raw OCR device:
    $ ocrcheck

    VOTEDISK:

    On 10g if using the raw device for OCR + votedisk: recommend 1 file = 250M

  • How to calculate the execution time of a SCTL in FPGA VI?

    Hello

    Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

    Thank you and best regards,

    Rashid

    Hello r,.

    A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

    It's all simple arithmetic. The inverse of the sampling frequency power of samples is then the dt or the time between samples the number of samples is not relevant.
