I've been getting a persistent little error lately.  It doesn't seem to
hurt anything, but I'm not sure if it's an indication of a bigger
problem.

The problem occurs when I am checking in new scratch tapes to replace
copy pool tapes sent off site.  The command I'm using is:
  checkin libv 8mmlib status=scratch search=yes checkl=yes

Following is a portion of my activity log:
06/11/97   17:06:25  ANR8422I CHECKIN LIBVOLUME: Operation for library
8MMLIB
                      started as process 69.
06/11/97   17:08:23  ANR8430I Volume A00057 has been checked into
library
                      8MMLIB.
06/11/97   17:10:13  ANR8430I Volume A00056 has been checked into
library
                      8MMLIB.
06/11/97   17:13:04  ANR8443E  : Volume A00028 in library 8MMLIB cannot
be
                      assigned a status of SCRATCH.
06/11/97   17:15:38  ANR8304E Time out error on drive 8MMBOT (/dev/mt0)
in
                      library 8MMLIB.

As you can see, ADSM is trying to checkin tape A00028.  That tape is
already known to ADSM as follows:

    q vol a00028 f=d
                  Volume Name: A00028
             Storage Pool Name: AIX_TAPE
             Device Class Name: 8MMTAPE
       Estimated Capacity (MB): 4,944.0
                         %Util: 37.5
                 Volume Status: Filling
                        Access: Read/Write
        Pct. Reclaimable Space: 44.4
               Scratch Volume?: Yes
               In Error State?: No
      Number of Writable Sides: 1
       Number of Times Mounted: 22
             Write Pass Number: 1
     Approx. Date Last Written: 06/11/97   00:59:51
        Approx. Date Last Read: 06/11/97   04:10:51
           Date Became Pending:
        Number of Write Errors: 0
         Number of Read Errors: 0
               Volume Location:
Last Update by (administrator):
         Last Update Date/Time: 06/05/97   23:08:29

It's always this tape or one other.  My question is why is ADSM telling
the drive to pull that tape and check it in as a scratch tape?

For info:  ADSM Version 2, Release 1, Level 5.11
              AIX 4.1.1
              IBM 7331 tape drive (robot)

Thanks in advance for any pointers...
