4.2 Discovering a storage array

To discover a storage array use the following syntax:

create StorageArray plugin=value storageType= { FIBRECHANNEL | ISCSI | LOCAL | UNKNOWN } [ storageName=value ] [ accessHost=value ] [ accessPort=value ] [ accessUsername=value accessPassword=value ] [ useChap= { Yes | No } ] [ adminHost=value adminUserName=value adminPassword=value ] [ pluginPrivateData=value ] name=value [ description=value ]

For example:

OVM> create StorageArray plugin="Oracle Generic SCSI Plugin" name=MyISCSIServer \
  storageType=ISCSI accessHost=10.172.76.130 accessPort=3260

For more information on the syntax and usage, see Section A.47, “create StorageArray” .

After discovering a storage array, you should attach at least one admin server to it so that administrative operations can be performed on the storage array by Oracle VM Manager. To add an admin server to the storage array, use the syntax:

addAdminServer { FileServer | StorageArray } instance server=value

For example:

OVM> addAdminServer StorageArray name=MyISCSIServer server=MyServer

For more information on the syntax and usage, see Section A.4, “addAdminServer” .

Next you should add the storage initiators to an access group for each Oracle VM Server that is to be granted access to the storage. In this example we add the storage initiators for each Oracle VM Server to the default access group that is created when a storage array is discovered. First, find the name of the access group by listing the access groups for the server using the show StorageArray command, for example:

OVM> show StorageArray name=MyISCSIServer
  ...
  Access Group 1 = Default access group @ MyISCSIServer @ 0004fb00000900005264cefc5b9a1cb8
    [Default access group @ MyISCSIServer]  Access group name
  Storage Plug-in = oracle.generic.SCSIPlugin.GenericPlugin (1.1.0)  
    [Oracle Generic SCSI Plugin]
  ...

Next, find the storage initiator name for each Oracle VM Server using the show Server command, for example:

OVM> show Server name=MyServer1
   ...
  Storage Initiator 1 = iqn.1988-12.com.oracle:e774e056fd3
         Storage initiator name
  Storage Initiator 2 = storage.LocalStorageInitiator in 
    00:e0:81:4d:40:f5:00:e0:81:4d:40:be:00:e0:81:4d
  ...

Then add the storage initiator for each Oracle VM Server to the default access group using the syntax:

add StorageInitiator instance to AccessGroup instance

For example:

OVM> add StorageInitiator name=iqn.1988-12.com.oracle:d72d82d0817f to AccessGroup \
  name='Default access group @ MyISCSIServer'

For more information on the syntax and usage, see Section A.13, “add StorageInitiator” .

Validate the storage array. Validation should be performed when any changes are made to the storage. To validate the storage array, use the syntax:

validate StorageArray instance

For example:

OVM> validate StorageArray name=MyISCSIServer

For more information on the syntax and usage, see Section A.161, “validate” .

Refresh the storage array so Oracle VM Manager has the most current information about the storage. To refresh the storage array, use the syntax:

refresh { AccessGroup | Assembly | FileServer | FileSystem | PhysicalDisk | Repository | Server | StorageArray } instance

For example:

OVM> refresh StorageArray name=MyISCSIServer

For more information on the syntax and usage, see Section A.124, “refresh” .
