[SunHELP] Reconfiguring an A1000

[Werth, Dave]

Nadine,

Ah... Thanks for clearing that up for me.  I do know about the sun service
'explorer' tool.  I last used it about 3 years ago.  I just didn't connect
it to this issue.
 
The disks I'm replacing have no system software on them (and nothing to do
with booting or the basic running of the system).  I just plan to disable
the Oracle and ERP software startups during the upgrade.  The metadata,
vfstab, etc files will still be available but since I will be changing them
during the process I'll save copies of the originals just in case.

Thanks, Dave

There is a tool, called "explorer" available from Sun that basically
collects all the configuration info from a server and stuffs it into
an archive which can then be mailed.

This is often the very first thing a Sun SE will ask for if you call
about a problem with your servers.

>From my perspective, key things to have in another electronic
location, over and above a known good backup, would be:

a) original "metadata" -- either metadb copies or however your RAID
manager deals with such info (i.e. what disks are in what RAID group,
how they are sliced if it's a partition based RAID manager, etc)
b) related configuration files -- vfstab, VTOCs and which devices have
which VTOCs

The suggestion of labelling which old disks go into which slots is a
good one as well.

Good luck with your upgrade.
