Larry,

if these the rather old HP-IB disk arrays you should become carefully: they will
no longer supported from 6.5 onwards.

We're still using such devices on the Sys_Vol only and do not have had problems.
It's recommended to have an H/W contract with HP or an official partner. In case
of a problem on one module you need to run FLEXDIAG which is a password
protected tool within SYSDIAG.

On private volumes we prefer Mirrored Disk and cheap SCSI disks.

Best regards, Andreas Schmidt, CSC, Germany

Subject:  RAID5 Disc's



I recently inherited a HP3000/987 with a RAID5 disc array sitting on the
floor next to it.  This disc system has not be installed yet.  Currently
I am running 5.5 pp6.  Who out there has a RAID5 attached to a system
running 5.5 and what are your pro's and con's concerning it?

Note:
My first day on the job ldev 2 crashed and burned causing me to do a
complete install once HP replaced the bad drive.  So I'm asking myself
why didn't this disc array get installed sooner?


Thanks in advance for your comments and suggestions.

Larry
