Re: V7R3 Upgrade tape library missing

Just curious here. Maybe not relevant. At one point, I don't remember the
details, the tape drive we had could not be seen. IBM suggested turning
the power off on the drive itself and then turning the power back on.
Worked. I am wondering if when entire system is shut down and restarted,
that if something doesn't report in on time, that it is ignored. There was
an IPL failure on our ancient B50 at another employer. CE said that if the
drive did not report in on time, it was stopped. Several power cycles and
the drive did report in and all was well. Something about the drive taking
too long to spin up. Which is why I am wondering if the library itself is
power cycled, whether that makes any difference.

Art,

Another possibility is that it didn't report it at all, which would
explain the not detected.
Do you have an HMC.
If so, once we find the correct adapter, we can add that adapter.

WRKMLBSTS shows TAPMLB01 varied off, vary on says reset required IIRC,
we've never varied that on.

TAP02 and TAP03 are still the only devices there.

Thanks, Art

Art,

I've seen similar behavior following IPL.
Sometimes the library reports in with a different name.

Try WRKMLBSTS
And
WRKCFGSTS CFGTYPE(*DEV) CFGD(TAP*)

If found with a different name, you can rename back to orginal.

TAPMLB01 is not detected and TAP02 and TAP03 resources aren't either.

This is a two partition system, we upgraded the one partition fine (it
uses the internal tape), then saved the other partition to the library
and system saved to TAP02, upgraded and PTF'd.

Trying to do a system save again and they are missing. We had this
problem a few weeks ago when attempting to test the tape drives before
the upgrade, IBM service came in and told us to power down all
partitions, power down the server, then power server up, power up
partitions. that worked.

I'm wondering why this would happen after an upgrade. Makes me think
there is something wrong with hardware? We are going to call IBM.

We don't need the tape drive for production, but it would have been
nice to get that V7R3 system save done tonight.
