Using LEDs to diagnose problems
The storage system LEDs provide system status and diagnostic indicators.
If the storage system used in a remote TrueCopy configuration restarts with
the TrueCopy status of enabled, the following occur:
• The path used by TrueCopy becomes blocked. Notifications from the
Hitachi Device Manager - Storage Navigator email alert function, SNMP
Agent Support function, and SNMP trap occur when the path is blocked.
Follow the instructions in the notification. The blocked path recovers
automatically after restarting the storage system.
• If the TrueCopy pair status is PAIR or COPY, the pair changes to PSUE. In
this case, suspend the pairs before restarting the storage system.
