This SOM determines the action that will be taken
when the status of an external volume is Not Ready.
Mode 725 = ON:
When Not Ready is returned, the
external path is blocked and the path status can be
automatically recovered (Not Ready blockade). Note
that the two behaviors, automatic recovery and
block, may be repeated.
When the status of a device is Not Ready blockade,
Device Health Check is executed after 30 seconds.
Mode 725 = OFF (default):
When Not Ready is
returned three times in three minutes, the path is
blocked and the path status cannot be automatically
recovered (Response error blockade).
Notes:
1.
Applying this SOM is prohibited when USP V/VM
is used as an external storage system and its
external volume is DP-VOL.
2.
Applying this SOM is recommended when the
above condition (1) is not met and SUN storage
is used as an external storage.
3.
Applying this SOM is recommended when the
above condition (1) is not met and EMC CX
series or Fujitsu Fibre CAT CX series is used as
an external storage.
4.
Applying this SOM is recommended if the above
condition (1) is not met and a maintenance
operation such as
firmware
update causing
controller reboot is executed on the external
storage side while a storage system other than
Hitachi product is used as an external storage
system.
5.
While USP V/VM is used as an external storage
system and its volume is DP-VOL, if some Pool-
VOLs constituting the DP-VOL are blocked,
external path blockade and recovery occurs
repeatedly.
6.
When a virtual volume mapped by UVM is set to
pool-VOL and used as DP-VOL in local storage
system, this SOM can be applied without
problem.
