Re: A3700 raid array
1) Analyze the data on the system.
2) Back it up.
3) vgexport volume group.
4) replace disk with larger disk.
5) rebuild volume group and filesystems
6) restore data
This op requires downtime.

Re: A3700 raid array
1) Backup all data stored on the 12H.
2) Pull one of the 9GB drives.
3) Wait for the array to rebuild to the active hot spare. This may take hours. Rebuild progress will be displayed on the LCD screen, or may be obtained via 'arraydsp'.
4) Insert one of the 36GB drives.
5) Wait for the array to balance.
6) Repeat steps (2) through (5) three times.
Note that to make all of their space available, drives must be installed in pairs. No downtime is required, although there will be a massive performance hit during rebuild operations. This effect can be lessened by decreasing the rebuild priority, although this will obviously cause the rebuild to take longer.

Re: A3700 raid array
You must wait for the array to rebuild before inserting the new drive.

SolutionThe good news is that the array can continue to do its normal work while this is going on. I have upgraded several 12H's from 9.1GiB drives to 36.4GiB drives while the arrays were quite active and running databases. It took 2 0r 3 days to complete the one at a time replacement but the databases never skipped a beat.

Re: A3700 raid array
I actually placed a call to HP storage the first time I had to replace a drive in a 12H. The technician made it patently clear that the rebuild was to finish before the replacement drive could be installed.

Re: A3700 raid array
work just fine. Of course, I'm not sure I would ever trust anything I got from some idiot (like me) on the internet or some idiot who works for HP. That's why I always do things first on my sandboxes.
