IT35537: POOL NAMES BEING DISPLAYED INCORRECTLY WHEN LOOKING AT VOLUMES

APAR status

• Closed as program error.

Error description

• Storage Insights has been observed to display SVC volumes
  associated with pool names that do not exist on the storage
  device that these volumes are hosted on.
  This display issue
  changes over time:
  The volumes will be associated with the
  correct pool names immediately after the daily probe task is
  run; then slowly over the course of the next several hours, the
  volumes no longer show up associated with the correct pools,
  and instead show up in pools that are on systems not
  virtualized by the same SVC.
  The problem is caused by
  event-miniprobe processing; incorrect associations are a
  byproduct of thread-local cache containing identifiers that may
  not be unique.
