Description
1. This SOM is set to ON to have SIM for users reported to
the service personnel:
• For the system where SNMP and E-mail notification
are not set.
• If Device Manager - Storage Navigator is not
periodically activated.
2. When SOM 734 is turned OFF, SIM-RC625000 is not
reported; accordingly the SIM is not reported to the
service personnel even though this SOM is ON.
Enables to change the area where the information is obtained
as the Characteristic1 item from SYMMETRIX.
Mode 745 = ON:
• The area where the information is obtained as the
Characteristic1 item from SYMMETRIX is changed.
• When CheckPaths or Device Health Check (1/hour) is
performed, the information of an already-mapped
external volume is updated to the one after change.
Mode 745 = OFF (default):
• The area where the information is obtained as the
Characteristic1 item from SYMMTRIX is set to the default.
• When CheckPaths or Device Health Check (1/hour) is
performed, the information of an already-mapped
external volume is updated to the default.
Notes:
1. This SOM is applied when the EMC SYMMETRIX is
connected using UVM.
2. Enable the setting of EMC SCSI Flag SC3 for the port of
the EMC SYMMETRIX storage connected with the
storage system and disable the setting of Flag SPC2. If
the setting of EMC SCSI Flag SC3 is not enabled or the
setting of Flag SPC2 is enabled, the effect of this SOM
may not be achieved.
3. If you want to enable this SOM immediately after
setting, perform Check Paths on each path one by one
for all the external ports connected to the EMC
SYMMETRIX storage. But, without doing Check Paths,
the display of Characteristic1 can automatically be
changed by the Device Health Check to be performed
once an hour. If SSB=AD02 occurs and a path is
blocked, perform Check Paths on this path again.
This SOM disables the HDP Rebalance function and the HDT
Tier relocation function which allow the drives of all ECC
Groups in the pool to share the load.
Mode 749 = ON: The HDP Rebalance function and the HDT
Tier relocation function are disabled.
Mode 749 = OFF (default): The HDP Rebalance function
and the HDT Tier relocation function are enabled.
Notes:
1. This SOM is applied when no change in performance
characteristic is desired.
