APAR status

• Closed as program error.

Error description

• A Tivoli Storage Manager lanfree backup or archive can fails
  with "no space available in storage pool".
  .
  From Tivoli Storage Manager / storage agent activity log shows:
  .
  ANR0522W (Session: 4321, Origin: NODE) Transaction failed for
  session 1234 for node TDP_NODE (TDP Oracle SUN) - no space
  available in storage pool STGPOOL and all successor pools.
  .
  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 storage agent 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:
  medium

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.
