How to check physical disk license on 3PAR

Recently we were involved in disk upgrade task on an HPE 3PAR storage array. The task was pretty simple with two action items. First one was to verify the newly added physical disk and second task was to verify additional physical licenses.

To complete the task, we have used few commands with additional options. The main commands were,


showpd 
showlicense

Let's look those in detail.

Once new physical disks are inserted, run showlicense to check if the array has sufficient license available to accommodate newly added disk

If you check the output, you can see that this array is licensed for 64 physical disks. This array initially had 32 physical disks and we added 32 more. Based on the license this array is good to accommodate 64 physical drives in total.

if  appropriate number of physical disk license available, then run showpd command to check the installed disks.

Output truncated.

check the output and ensure that you are able to see all 64 drives.

That's it for now. Will continue with the manual chunklet initialization and tunesys in next post.
