RE: Changing out drives on a 170: any "gotchas"?

["Nate Gelbard" <gelbardn@xxxxxxxxxxxx>]

Will the 170 accept non-IBM part number SCA drives?

My 170 has 4x8g drives and an empty expansion bay.
I'd like to throw a couple 73gig SCA drives in there.
The prices for IBM 170 drives are insane for the $/meg.

Will it work with aftermarket parts?

The 170 already has hot plug cages with SCA ports (no SCSI ID needed).
So the mechanical part becomes easy.

Whether you need to take any special precautions depends on a lot of
factors.

a) What kind of protection is in place? Mirrored? Parity?
b) What kind of disk are you replacing (Load Source?)
c) What version of OS are you running?

The InfoCenter is always a helpful resource, but there's no Infocenter
that still has Infos on a Model 170.

If you read through that stuff you should be able to figure out what
you need to do, but there's a lot of moments where you need to rethink
for the older hardware and OS.
