I have a Compaq TRU-64 Alpha box that seems to have a six-drive RAID
physically installed, but not accessible at the moment. The following
is the output of a number of diagnostics, and I was hoping that
someone knowledgable could give me some pointers on finding the device
name(s) of the drives, and how I might then best use mkfdmn, mkfset,
etc. to put them into service. Many thanks.
Diagnostic commands issued below:
1) /usr/sbin/disklabel
2) /sbin/hwmgr -view devices
3) ls -l /dev/disk/
4) /sbin/showfsets root_domain
5) /sbin/showfsets usr_domain
6) /sbin/showfsets tmp
7) /sbin/advfs/advscan -a
8) /sbin/advfs/advscan -ag
