Resolving Invalid Cache Error Messages—Serial Number Mismatch
Error Messages
An invalid cache error message may display after the SHOW
THIS_CONTROLLER command is submitted. The controller reports that the
cache and mirrored cache with cache are invalid and that the cache should be
installed in a specific controller with the serial number ZGxxxxxxxx.
Caution: Failure to clear an invalid cache message (especially a “Cache is
FAILED” message)
before setting the Failover mode can result in a recursive
bugcheck error message that renders the controller unusable.
To resolve an invalid cache error message, see Table 3 on page 52.
