Hi TSMers,

My environment is
                   Fiber                   SCSI
RS/6000(TSM Server) ----> 2108 SAN Gateway -----> 3584 LTO library.


The TSM server worked perfectly until yesterday. The tape drives all went
offline and the problem turned out to be the hardware failure of 2108.

IBM technician came and replaced the 2108. After that, I updated the
latest
firmware for 2108 re-configured the 2108.


I have  followed the startup subsquence:
1. Turn on 3584 library;
2. Turn on 2108, initializeBox, targets, etc, reboot 2108
3. Restart RS/6000

Everything seemed fine, I can see all the devices on AIX, and inquery ok.

However, after I started up the dsmserv,

I got such errors:

But there is no error from errpt.


Any advice will be appreciated!

Jason,

The first thing I would do is do an "audit library" and see if that
helps.  I am guessing this is a large library since you have 8 drives.
But it still might be worth the time, since it should correct the problems.

If the "audit library" didn't help then this might be a stretch, but I
saw something like this once.  The customers robot was misaligned.  The
bar code reader was reading the right volume, but the robot was grapping
the wrong tape ( it was actualy grapping the tape next to it ).

I would look and see which tape was supposed to be mounted and which
tape the robot was actually picking.

Again let me be clear, I am taking a stab at this one.  It just sounds a
whole lot like what happened before.  Good Luck and let us know what it
was when you get it fixed.
