SPM adapter for EMC® Symmetrix® VMAX®: Matrix support for automation of EMC storage operations via the HP Storage Provisioning Manager

Technical white paper | SPM Adapter for EMC Symmetrix VMAX

The remote server returned an error: (401) Unauthorized

This error may occur while the SPM adapter is sending a request to the EMC Symmetrix VMAX array management server.

• Possible Cause:

– This error may occur if the given username or password is invalid.

• Suggested Action:

– Retry the operation with valid username and password.

The operation has timed out

This error may occur when the SPM adapter had sent a request and was waiting for the response from EMC Symmetrix

VMAX array management server, but the response did not arrive within the expected time window.

• Possible Cause:

– This error may occur due to network delays.

• Suggested Action:

– Increase the http timeout value (in milliseconds) in the adapter configuration file

• Open adapter configuration file located at C:\Program Files (x86)\HP\Storage Provisioning

Manager\plugins\storage_adapters\EMCSymmVMAX\EmcSymmetrixVMaxAdapter.exe.conf

• Change the value assigned to HttpTimeout key to an appropriate value. The default value is set for 5 minutes.

Failed to refresh resources from adapter 'EMCSymmVMax'

• Possible Cause:

– This error may appear in the SPM log file if the adapter had been previously enabled and array objects were imported

and the adapter was later disabled without removing the array from SPM.

• In this scenario, SPM keeps trying to refresh the resources and fails to invoke the adapter. An exception will be

thrown on the SPM log:

Exception

- Message: No such adapter: EMCSymmVMax

• Suggested Actions:

– To avoid this error, perform one of the following actions:

• Enable the adapter and let SPM to continue with refresh resources operation

• Remove the imported EMC array(s). If the adapter needs to be disabled permanently, check if any of the SPM

services are bound to EMC array, it may be required to deactivate the services before removing the imported EMC

arrays.

Storage pool setting does not exist for the given RAID

• Possible Cause:

– The storage pool setting (Symm_StoragePoolSetting) object does not exist for the given RAID level.

• Suggested Actions:

– The EMC Storage administrator needs to create a volume of given RAID level through EMC native management tools

(like SMC or SYMCLI). This creates storage pool setting object that supports a given RAID level.

Growing thin volume feature is not supported

• Possible Cause:

– User may have selected a thin volume to grow to the required capacity.

• EMC doesn’t support growing a thin volume. The selection of growing a thin volume (as shown in Figure 9) would

result in this error.
