HD mirror set

How long should it take (realistically) for a mirror set made of 36.4GB
(10k) u320 HDs to synch on a 2.8GHz server w/ 2GB of RAM?

No, no percentage completed shown. Just shows it's resyncing. It's an
onboard LSI card in an ibm x345.

Haven't seen where I can set rebuild priority on this LSI card.

This is a nw 6 server, doing pretty much nothing during the day, but
runs our backups at night. Am sitting at over 24 hours now trying to
synch a couple of 36GB drives.

Hoping not to get thwacked for asking about this, as I'm not asking for
Netware support, asking more along lines of support in the server LSI
card bios.

I cited NW 4.2 -- not much in the way of currently supported, eh?

Bummer -- with NW 4.2 I can query and get a remirror status number --
reduces the stress level while waiting for the remirror to complete.

Well, on the NetWare side -- you might ask over in the 6x storage
newsgroup. As to the LSI status information -- that I can't answer -- I
don't load any utilities to see that while the OS is loaded and the
mirroring action is generated from the server OS for me.

Might have to do that. Didn't think it was a nw issue, as I figured
the mirroring was done @ the card level.

Ah, IBM servers... You might have that LSI SCSI firmware bug that causes
constant sync. What BIOS is your x345 running? Version 1.18 fixed it.
Version 1.21 fixed further problems with data scrubbing.
