ailure messages you may have received from system
monitoring
(System Event Analyzer).

CAUTION:
If you are running HP StorageWorks Command View EVA 4.0,
the power supply numbering presented in the management
interface is inconsistent with the numbering used in the storage
system and reported by the ISEE/WEBES monitoring tool. HP
Command View EVA 4.0 identifies the left power supply as 1
and the right power supply as 2. The correct numbering should
be 0 and 1 respectively. Remember to make this conversion
when replacing a power supply. This inconsistency is corrected
in later versions of HP Command View EVA.
