Simpana 9 Oracle or File System SnapProtect Failure via NetApp

Had an interesting condition in the last few days and really thought I would share, as it seemed like something really simple that could be checked by anyone.

Likewise, this could affect Oracle and/or File System SnapProtect jobs via NetApp.

Error: 62:2145

Description: The client machine initiator address is not visible on the file server. Please check the SAN or iSCSI connectivity between the file server and the client.

Upon reviewing this one, I identified the following conditions;

First connection to the FileServer completes, however…

As you can see the next attempt fails… The final attempt will be to determine if the HBA’s from the client can be seen against the FileServer. Should we also get failures again connecting to the FileServer it will fall through with the error below.

Things we have learnt, if communication between Client and Fileserver is impacted, it can cause the failure above. So be sure to validate that communication between the client and Fileserver is not affected.

Side note, if you wish to lock down the Simpana to use http vs https for the ManageONTAP communication you can use the registery key below;

s<arrayname>_NETAPPONTAPUSEADMINTRANSPORT

Defined under the iDataAgent branch of the simpana registry. Where the value of the key is http or https.

i.e. Example

vi /etc/CommVaultRegistry/Galaxy/Instance001/iDataAgent/.properties
Add line;

sLBnNNNnn-n_NETAPPONTAPUSEADMINTRANSPORT http

Now our communication will be http to FileServer LBnNNNnn-n, per regkey.
