Re: Array Expansion On MSA1000 running HP UX 11.11/23

Hi,

Will there be any impact if I were to add on hard disk and expand the array online? Will data be lost?

I wish I could say 100% yes, but I've never seen or experienced a problem. Heck, even PHD's loose spacecraft due to human error.

Always have a fresh backup, when performing any operations on your data.

The first thing I would do is set the expansion priority to high. Perform your expansion.

Hi,

it is always better to have a backup.
Expanding the array does not effect the OS.
But do NOT expand logical drives. Until now HP-UX 11.11/23 is not able to handle this.
Doing so is a waste of disk space. You have to create new logical drives and add them to your VG configuration.

Hope this helps!
Regards
Torsten.

Hi All,

Appreciate your answers and thanks for your help.

But I wasn't able to find any documentation to show that the method is not supported.
