Hi Bryan,
I answered your other post asking about seeing VIF paths via powershell and I figured I'd take a stab at this one. I've spent quite a bit of time digging through the GUI and the ucs cmdlet metadata and I'm not positive this can be done. Here is where I ended up:
In the GUI, I *think* the controller cache size would be shown here in the GUI. Note we do not have any C-series blades and the cache is marked as disabled on all of our B-series blades.
If you right click on the selected Virtual Drive and choose "Copy XML" you can see the ClassID of the object Here is the output for me with the classid and cache part bolded:
<storageVirtualDrive accessPolicy="read-write" actualWriteCachePolicy="write-through" adminActionTrigger="idle" adminName="" adminState="undefined" availableSize="unknown" blockSize="512" bootable="true" changeQualifier="" childAction="deleteNonPresent" configQualifierReason="N/A" configState="orphaned" configuredWriteCachePolicy="write-through" connectionProtocol="unspecified" deployAction="no-action" dn="sys/chassis-1/blade-2/board/storage-SAS-1/vd-0" driveCache="disable" driveState="optimal" id="0" ioPolicy="direct" lc="allocated" locale="" model="" name="" numberOfBlocks="583983104" operDeviceId="0" operQualifierReason="N/A" operState="undefined" operability="operable" presence="equipped" readPolicy="normal" revision="0" serial="" size="285148" stripSize="64" type="mirror" uuid="43565d32-e7d9-4886-a128-fb8491db77f8" vendor="" vendorUuid="6f8c2886-738c-2000-1c07-7cd60be3c578"> <storageOperation childAction="deleteNonPresent" endTime="2015-12-12T03:22:46.000" name="consistency-check" operState="completed" progress="unknown" rn="op-consistency-check" startTime="2015-12-12T02:46:41.000" statusDescr=""/> <storageVDMemberEp childAction="deleteNonPresent" configQual="no-action" configState="not-applied" deployAction="no-action" diskDn="sys/chassis-1/blade-2/board/storage-SAS-1/disk-2" id="2" model="" operQualifierReason="N/A" operability="unknown" presence="equipped" revision="0" rn="member-2" role="normal" serial="" spanId="unspecified" vendor=""/> <storageVDMemberEp childAction="deleteNonPresent" configQual="no-action" configState="not-applied" deployAction="no-action" diskDn="sys/chassis-1/blade-2/board/storage-SAS-1/disk-1" id="1" model="" operQualifierReason="N/A" operability="unknown" presence="equipped" revision="0" rn="member-1" role="normal" serial="" spanId="unspecified" vendor=""/> </storageVirtualDrive>
I played around quite a bit with various methods to try and query this but I was not successful. This is the output of Get-UcsCmdletMeta -ClassId storagevirtualdrive. Not the Verb field is empty. There might be some way to pull this out via the XML (via powershell) but that's beyond my skill set. I'd love to hear if there is a way to do this
ClassId : StorageVirtualDrive
Noun : UcsStorageVirtualDrive
Verb : None
PipelineClassId : {}
LimitScopePipelineClassId : {}
MoMeta : Cisco.Ucs.UcsMoMeta
