[Orca-users] Re: Orcallator on Solaris 10

[Cockcroft, Adrian]

Also try running # se disks.se
This should give you the full set of disks and mappings, if it also
crashes then there needs to be a generic fix in SE rather than a fix in
Orcallator

Devfsadm -C worked for one of the systems that has no SAN drives
currently 
attached, but did not work for the others.  I still get Segmentation 
Fault on those.  Thanks for the suggestions.

I am using Version 3.4 of SE.  I never tried another version with
Solaris 
10, cause I thought I needed 3.4 on this.

I will look into the iostate class more closely.

Timefinder not an option for us with Clariion, but we do something very 
similar by manually rewriting diskid and importing mapfiles of snapped 
veritas volumes.
