omnimm -repository_update Issue

Is there any setting to have the omnimm -repository_update command wait a little longer between tape loads? Anything in the global file?

Background:
I have an L2000 with a Surestore 1/9 attached to it. Tapes consistently get stuck in the drive when doing a repository update. I have switched hosts, switched cables, terminators, tapes, reset to factory presets, recreated picker file, etc. HP has been in and brought and installed a brand new unit.
I gave up for a while and used it with 1 tape while I was on other projects. I've been testing it over the past few days and it seems that there is a delay unloading a tape from time to time and omnimm is issuing the command to load the next tape, causing a hard error (overlapping commands).

If I have one tape in, I can do a repository update till I'm blue in the face and it's fine. When there are multiple tapes it's a crap shoot.

This part is even stranger: If I use HP DLTs the tape just jams in the drive. If I use Quantum or Fuji it will actually rip the leader off the tape.

Either way, I'm up for anything at this point.

Thanks...
Jim

Re: omnimm -repository_update Issue

There are a series of variables that can be set to adjust omniback timing for tape commands, but I am not sure any of them will really be relevant here.

They are to be placed in the .omnirc file of the host connected to the tape drive - thus affecting tape drives on ONLY ONE HOST.

In general I think you are interested in the SLEEP variables.

OB2DEVSLEEP=
OB2REWINDSLEEP=
OB2OFFLINESLEEP=
OB2XS2SLEEP=

The sleep variables values are in seconds...

So for testing purposes, I propose you try these set to fairly large (arguable unreasonably large) values such as

OB2REWINDSLEEP=180
OB2OFFLINESLEEP=180
OB2XS2SLEEP=180
OB2DEVSLEEP=180

If that actually does useful things for you, trim them down to more reasonable values along the lines of 45 seconds...

I do not know if these will affect the repository update command - it is my guess they will.

I also do not know if any of these are the right variables for your scenario.

For tuning this, consider a call to the response center - there are also a few other SLEEP variables - but they are fairly "special case".

Good Luck.
Omniback and NT problems? double check name resolution, DNS/HOSTS...
