The Power Led Does Not Turn On - Hitachi AMS 2000 Series Service Manual

NOTE: When a base unit is used as the remote unit in a TrueCopy remote
replication/TrueCopy Extended Distance configuration, restarting the base
unit can cause the following events:
• Both paths of TrueCopy remote replication/TrueCopy Extended
Distance are blocked.
• At the time the path is blocked, Navigator 2 sends a failure notice to
the users whose email addresses are configured in the Alerts and
Events window in Navigator 2. The alert contains information regarding
the Email Alert and SNMP Agent Support features, and TRAP. Follow
the instructions in the email alert. After the remote unit has restarted,
the path blockade automatically recovers and the paths are available
for use.
• If the pair status of TrueCopy remote replication/TrueCopy Extended
Distance is PAIR or COPY, the pair status changes to PSUE.
• When the base unit must be restarted, change the pair status of
TrueCopy remote replication/TrueCopy Extended Distance to PSUS,
and then restart the unit.
NOTE: When the Power Saving storage feature is used, if you restart the
base unit while the spin-down is in progress, the spin-down may fail
because it recognizes the host immediately after the unit starts.
After the spin-down has completed, check the RAID Groups and make sure
that none of them are set to the "Normal (command monitoring)" power
saving status, then restart the unit. If the spin-down fails, start the spin-
down again.
