Re: adding disks

Are you buying the disks new from IBM? In that case there's an 'idiot's
guide' that can't go wrong. I added two disks last year to an 810, and
the guide offers two roads, one dedicated (power off, insert the disks,
power back on, and add them to the RAID set) and one using concurrent
maintenance (leave the system running, insert the drives while LED is
blinking, and add them to the RAID set). I used the latter and it went
flawless.

I'd expect the instructions to be in the Information Center, an IOP and
LVD SCSI card installation I had done recently by IBM (they were there
to replace a cache battery anyway) only came with URLs, no more printed
instructions. So even if you don't get the drives new, the info should
be available.

One thing to be aware of is the latch on the drive's tray. When you pull
it out, it stops at about 70 degrees angle. You have to apply a bit of
force to extend it the full 90 degrees, or it'll catch on the frame,
preventing the drive from being inserted.

You've got between 30 and 60 seconds to install the drive, if you miss
the window you just wait 60 seconds and the LED will start flashing
again, giving you another go. Don't remember off hand if I had to go
through DST (FrontPanel 21, enter) or that SST was sufficient.

Best use a wrist strap or proper grounding techniques before sliding in
the drives.

I am adding two disk drives to an 810. I am adding them to a "raid"
set.

Does anyone know the manual that would have instructions to do this?
I'd like to see the following:

- how to install physically
- how to initialize
- how to add to the raid group

I assume the initialize and add to the raid group are done through
sst, but do I install them physically, then reboot, and then just go
into sst, or do I have to reboot to Dedicated Service tools to add
them?

Appreciate any pointers.

thanks,
