Subject: [Veritas-bu] drives going down on media servers
I have 1 master server, and 2 media servers connected over fiber to an
L700. Im not sure what the switch in the middle is as didnt install the
system or have any info on it.
There are 5 drives in the L700 and 3 of them are shared with sso option
to the master, and both media servers.
People i have had an issue lately with drives being not visible to one
of my media servers.
I have fixed this by unloading the fibre hba using cfgadm and loading it
again. It then can see the devices under sgscan and has seen them under
/dev/rmt
I also noticed the customer had removed a /etc/hosts entry for the media
servers to talk to each other by the correct name so i put that back in
and can now talk on port 13701 to each machine in the nbu setup.
Whats happening now though is drives just keep going down on the media
servers and backups are not working. I have ITC enabled so each media
server needs to lock 2 drives.
I have looked the bptm logs and cant see anything jumping out apart from
many request medias of different tape ids.
I have looked in /usr/openv/volmgr/debug/ltid/ and the logs in their
show successfully on communicating shared drive info to the master.
Therefore i am now stuck and have no idea whats going wrong :(
Anyone any advice/pointers? Is ether anything specific i should be
looking for in the logs or are there other important logs im not
checking.
Thanks

Subject: [Veritas-bu] Blocksize problem after upgrading EMC powerpath
(UPDATE)
Hello All
I have now by trial and error figured out that it wasn't EMC powerpath,
but Windows 2003 SP1 which puts a microsoft hbaapi.dll into system32 in
place of the emulex one.
At the moment there's hbaapi.dll (from microsoft, 64Kb limit) and
emulexhbaapi.dll (at least 256kb) in system32 on the servers in
question.
Now I just need to figure how to get the tape drivers to use the
emulexhbaapi.dll, any ideas ?
Regards
Michael

Have you tried /var/adm/messages (Solaris) or the equivalent log ?

Not to mention this is actually better for these types of drives than
letting them spin all day every day.

I believe it's bit more than JBOD. There are a couple of players in
this space (I think the Petabox is another). Essentially what these
boxes do is to spin up only 10% or so of the drives at any one time.
When you think of how you would use the disk, this makes perfectly good
sense. You write your incrementals to disk, and then likely don't use
it until you write over them again (or at least use them infrequently).
If you need to do a restore, the disk library automatically spins up the
right disk and makes it available. I think that operation takes about 2
minutes or so which would be comparable to a tape mount. The reads,
however, would be much faster. You then spin the disk back down again.
Since only 10% of the drives are spinning at any one time, you save a
*ton* of power and cooling costs.

Yep. There's messages about drives going down but nothing concrete as to
why.

Subject: [Veritas-bu] restore of clustered SQL database on virtual node

Hi, I backup a MS SQL Enterprise 2000 Cluster using the virtual node
name to backup the databases.I backup the OS of each physical node using
the physical hostname. I would like to restore these SQL databases at my
DR site and I have one server available for the restore. Is it possible
to restore the database to a server that is not a member of a Microsoft
cluster using the following options...
(a) non clustered server with physical hostname the same as the
original
(b) non clustered server with different physical hostname
Many Thanks. Mark
