Stable Backups... (What we run, and what was changed...)

I have to admit this took much time to get to a stable backup platform...

These is our environment that was working, mostly:
Sun Solaris 10u3 (T5240 sparc)
NetWorker 7.5.1
Sun StorageTek SL500 (6 drives)
EMC EDL (20 virtual drives)
Celerra with NDMP to EDL and SL500...

What fixed what....
#1) NetWorker 7.5.1 Roll-up 6, this has solved a few really annoying client
issues, and an index issue, but by itself appeared to do nothing to improve
uptime.

#2) We were running NMC on the Sun server, moved this to its own Windows box
and...
Indexer performed much better, especially around some MSSQL issues...
nsrim taking > 45 minutes to run...
Random crashes - nsrd would simply be locked kill -9 only way to shut it
down...
-- to be fair this is EMC Best Common Practice, but they should state
up front that your server requires two physical servers then...

#3) Upgrade of the EDL code.
EMC came out last week to upgrade our EDL code (and we were on a
fairly recent version already.
We were suffering from virtual devices randomly going offline locking
up necessary "tapes" some times stopping backups/clones/etc...
We were suffering from TapeAlert messages about wrong medium...

This combo of changes has made our system seem to operate much better, hope
this helps anyone out in a similar boat... its going to be difficult to
convince myself to upgrade things now though.. oh well Smile

Stable Backups... (What we run, and what was changed...)

Good info..

When you say " locking up necessary "tapes"" did those tapes show up as
"unlabeled" when devices would go offline? I'm running into issues with
some devices in my edl's going offline. I have "CDL" off also.

Ahh, I bet that's what's going on here. Thanks for the info..

We have two edl's and the problem is happening on both of them. I'll
come in one morning and about 1/4 of the drives will be in service mode,
and some of the tapes will show up as "unlabeled".

This morning I came in and all of my vcb proxy server drives were in
service mode..

Also, in my first post I meant to put that I have CDI off and not CDL..

No problem no problem... Yes that is the exact symptom and it has not
happened since the code upgrade, and last weekend was the full monthly
backup, so that means something.

Alec

If its any consolation we don't use VCB's here... we have about 500 VM's in
20 VMWare hosts.... We end up doing backups using NetWorker clients inside
of each guest. We'll be doing the host level "DR" solution via RecoverPoint
by end of year.

The code upgrade didn't help the issue... At least the issue is
consistent in both of my datazones. Smile

I'm going to make sure that I don't have issues down a certain fiber
path. I have the drives split between two fiber paths. I'm going to
make sure I'm not having issues with one of the paths.

Thanks

Stable Backups... (What we run, and what was changed...)

Have you enabled persistent naming for the virtual tape devices? Sometimes
the OS gets confused about which drive belongs to \\.\TapeX
<file://./TapeX>or the Unix equivalents.

Subject: [Networker] Stable Backups... (What we run, and what was

I have to admit this took much time to get to a stable backup
platform...

These is our environment that was working, mostly:
Sun Solaris 10u3 (T5240 sparc)
NetWorker 7.5.1
Sun StorageTek SL500 (6 drives)
EMC EDL (20 virtual drives)
Celerra with NDMP to EDL and SL500...

What fixed what....
#1) NetWorker 7.5.1 Roll-up 6, this has solved a few really
annoying
client
issues, and an index issue, but by itself appeared to do nothing to
improve
uptime.

#2) We were running NMC on the Sun server, moved this to its own
Windows
box
and...
Indexer performed much better, especially around some MSSQL
issues...
nsrim taking > 45 minutes to run...
Random crashes - nsrd would simply be locked kill -9 only way
to
shut it
down...
-- to be fair this is EMC Best Common Practice, but they
should
state
up front that your server requires two physical servers then...

#3) Upgrade of the EDL code.
EMC came out last week to upgrade our EDL code (and we were
on
a
fairly recent version already.
We were suffering from virtual devices randomly going offline
locking
up necessary "tapes" some times stopping backups/clones/etc...
We were suffering from TapeAlert messages about wrong
medium...

This combo of changes has made our system seem to operate much
better,
hope
this helps anyone out in a similar boat... its going to be
difficult
to
convince myself to upgrade things now though.. oh well Smile

Stable Backups... (What we run, and what was changed...)

I haven't, but for some reason the vcb proxy server couldn't see the
drives through the inquire. I rebooted it and all was well, gotta love
windows... J

Have you enabled persistent naming for the virtual tape devices?
Sometimes the OS gets confused about which drive belongs to \\.\TapeX
<file:///\\.\TapeX> or the Unix equivalents.

We have two edl's and the problem is happening on both of them. I'll
come in one morning and about 1/4 of the drives will be in service mode,
and some of the tapes will show up as "unlabeled".

This morning I came in and all of my vcb proxy server drives were in
service mode..

Also, in my first post I meant to put that I have CDI off and not CDL..

Yes that was definitely one issue we were experiencing. Try having
EMC come and upgrade your EDL's software.... Nice free easy to
implement fix.

Its so annoying to recreate physical problems in the virtual world for
the sake of completeness.

Stable Backups... (What we run, and what was changed...)

We had to delete and re-add the jukebox via NetWorker... well I do hope you
find the right answer, not sure if the combo of 7.5.1.6 + EDL code upgrade
resolved the issue or not... What level of NetWorker are you on?
