BackupExec 2012 (14) on newer Linux

Tuesday, August 6th, 2013

In particular – Oracle UEK, which “claims” to be 2.6.39-xxx, but is actually 3.0.x with a lower version number. Several misbehaviors (or differences) of version 3 can be found. One of them is related to BackupExec. The service would not start on OEL6 with UEK kernels. The cause of it is an incorrect use of a function – getIfAddrs. Everything can be seen in this amazing post. The described patch works, at least to allow the service to start. Check out the comments for some insights about how to identify the correct call.

I am re-posting it here, so it can be found for Oracle Universal Enterprise Kernel (UEK) as well.

NetApp “Broken disk label”

Thursday, August 1st, 2013

When using ‘disk show -v’ on a NetApp filer version 7.3.x, following replacement or addition of disk(s), you might see the above mentioned message. It is caused by incorrect disk label – of OnTap version 8, on an OnTap version 7.3.x system. The system cannot handle the incorrect label, and thus – ignores the disk.

A set of actions is required to clean the label and allow the NetApp to use this specific disk. The easiest method (although it will not be described here) would be to place the disk back in an OnTap 8 NetApp device, and clean the label from there, however, it is not always possible.

On your OnTap 7.3.x system, do the following (assuming you know the address of the disk, right?) – taken from NetApp’s forums here.

disk assign <diskid>
priv set diag
labelmaint isolate <diskid>
label wipe <diskid>
label wipev1 <diskid>
label makespare <diskid>
labelmaint unisolate
priv set

The fifth or sixth lines might fail to run, but still – the process will succeed as a whole.
