StoragePool expansion in VNX clariion

[Aditya]

Hi,

I am trying to expand StoragePool in VNX clariion using SMI-S. I am using "CreateOrModifyStoragePool" method with following parameters

ElementName : PoolName to be expanded

Pool : CIMObjectPath of the pool

size : Expected Size in bytes after pool expansion

After executing the command, I receive error "The specified object has an invalid number of disks."

The JobInstance looks like this

instance of SE_ConcreteJob {

  DeleteOnCompletion = true;

  Description = "Modify Pool array: APM00134700308 pool: filepool size: 3879731200 blocks name: filepool";

  ElapsedTime = "00000000000005.350000:000";

  ErrorCode = 1;

  ErrorDescription = "C:ERROR_CLASS_SOFTWARE F:ERROR_FAMILY_FAILED R:1900016 Cannot perform the requested operation. Invalid number of disks : 2 : 20018 : \"The specified object has an invalid number of disks.\"";

  InstanceID = "4086140585";

  JobRunTimes = 1;

  JobState = 10;

  JobStatus = "Failed - Pool Expand";

  LocalOrUtcTime = 1;

  Name = "filepool";

  OperationalStatus = {17, 6};

  Owner = "EMC_StorageConfigurationService";

  PercentComplete = 100;

  StartTime = "20140512182914.610000+000";

  Status = "Error";

  StatusDescriptions = {"Completed", "Error"};

  TimeBeforeRemoval = "00000000010000.000000:000";

  TimeOfLastStateChange = "20140512182919.960000+000";

  TimeSubmitted = "20140512182914.594000+000";

  UntilTime = "99999999235959.999999:000";

};

What could be possibly wrong?

Thanks,

Aditya

You have to expand using the right number of disks. Check the StorageSetting that is used by the pool. If you created the pool with 5 disks, you will need to increase the size in multiples of 5.
