I have a customer who wants to verify if their CUCM 9.1.1 disks Partitions are Aligned prior to proceeding with the 9.1.2 upgrade. Is there a TAC approved procedure that can be performed prior to the upgrade to validate the CUCM Partitions are Aligned?

Cisco TAC provided the following procedure:
The output will be something like this. The key is too look for partition to start at “128” This one does. If its something like 63. Then its not aligned.

When you log via CLI or to CCMAdmin, does it says they're unaligned?? If no, they're aligned.

Hi,
As far as I know when u login through GUI in Application Administration page , u get the message Partitions UnAligned/Aligned.
Let other members also share their ideas.

Hi Fred,
Thanks for providing this excellent info +5
You can see a reference to this in a 9.1.1 bug;
With the resolution of CSCug40943, the "show hardware" CLI command now also provides specific details for disk partitions (partitions are aligned when start sector value is evenly divisibly by 64). This DDTS is to update the documentation to reflect the addition of this information to the "show hardware" output.
Further, with the related enhancement CSCug69836 "Include partition alignment check in "VMware Installation" CLI & GUI", the VMware Installation information line now explicitly indicates whether the disk partitions are aligned or unaligned.
From;
Partition alignment/OVA deployment information missing from CLI DOC
Cheers!
Rob
