II11142: VOLUME LABEL CYL0 HEAD0 CORRUPTED USING IAM FROM INNOVATION

APAR status

• INTRAN

Error description

• An IPL of several LPARs received IEF503I UNIT 053D I/O ERROR .
  The volumes could not be brought back online so they were
  initialized and a full volume restore was performed to recover
  the data.
  
  The problem with the lost DASD label was caused by a product
  called IAM from Innovation.  If creating large IAM files
  (VSAM compression) in an SMS managed pool with limited space
  and STOPX37 space reduction is involved, IAM overlays the
  volume label when attempting to volume switch.
  An 0C4 can also occur in IAM module IAMDEFIN at offset x'60c'
  when STOPX37 has reduced allocation to no space.
  .
  The fixes provided by Innovation are:
  for IAM 6.1  P-61.0112 dated 93.074  - lost dasd label
  for IAM 6.3  P-63.0291 dated 98.083  - 0c4 abend in IAMDEFIN
  
  Additional Symptoms : IEC027I 737-08
