IC66921: LANFREE BACKUP / ARCHIVE MAY FAIL WITH ANR0522W NO SPACE AVAILABLE IN STORAGE POOL

APAR status

• Closed as program error.

Error description

• A Tivoli Storage Manager lanfree backup or archive can fail
  with "no space available in storage pool".
  Server processes like reclamation may also fail with the error
  message "There is insufficient space in storage pool".
  .
  Examples from the Tivoli Storage Manager activity log:
  .
  ANR0522W (Session: 4321, Origin: NODE) Transaction failed for
  session 1234 for node NODENAME (PLATFORM) - no space
  available in storage pool STGPOOL and all successor pools.
  .
  ANR1086E Space reclamation is ended for volume XXXXXXXX.
   There is insufficient space in storage pool. (PROCESS:
   805)
  .
  Server trace with flag ASVOL will show...
    Pool out of scratch with numScratch A1, numRsvdScratch A2 and
    maxScratch A3.
  ...where A1 + A2 >= A3
  .
  .
  The problem is caused by a timing problem with the
  Tivoli Storage Manager storage agent when disconnecting from the
  Tivoli Storage Manager server.
  .
  .
  *** Customer/L2 Diagnostics ***
  To verify this, run SHOW SSPOOL and look for the storage pool
  (STGPOOL) the lanfree operation will use it. In the reported
  case SHOW SSPOOL on the Tivoli Storage Manager server returned:
  ....
  MaxScratch=500
  ...
  NumScratchVols=13, NumRsvdScratch=487
  .
  The TSM server can allocate MaxScratch=500 volumes.
  But the server already has 487 scratch volumes reserved
  (NumRsvdScratch=487). It will allow maximum 13
  (NumScratchVols=13) additional volumes to be requested from
  scratch. The use of collocation needs more than 13 volumes.
  .
  The NumRsvdScratch value become abnormal large is the character
  of this issue.
  .
  To fix the problem, increase the MaxScratch value in the
  affected stgpool.
  .
  Tivoli Storage Manager Versions Affected:
  Tivoli Storage Manager  server 5.4, 5.5 and 6.1 on all platforms
  .
  Initial Impact:

Local fix

• - Run SHOW SSPOOL on the Tivoli Storage Manager server and
    locate the storage pool  for the use of the LANFREE
    operaton. Sum up "NumScratchVols+NumRsvdScratch".
    If this the sum is >= "MaxScratch" then increase
    "Maximum number of scratch volumes allowed"
    for the LANFREE storage pool by number of scratch volumes
    needed.
  - Another way to clear this up is to recycle the Tivoli Storage
    Manager server.
