745 Universal
Volume
Manager Enables to change the area where the information
is obtained as the Characteristic1 item from
SYMMETRIX.
M
ode 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 option is applied when the Characteristic1
item is displayed in symbols while the EMC
SYMMETRIX is connected using UVM.
2. Enable the setting of EMC SCSI Flag SC3 for the
port of the SYMMETRIX connected with Virtual
Storage Platform. If the setting of EMC SCSI
Flag SC3 is not enabled, the effect of this mode
may not be achieved.
3. If you want to enable this mode immediately
after setting, perform Check Paths on each path
one by one for all the external ports connected
to the SYMMETRIX. Without doing Check Paths,
the display of Characteristic1 can be changed
automatically by the Device Health Check
performed once per hour. If SSB=AD02 occurs
and a path is blocked, perform Check Paths on
this path again.
4. If Check Paths is performed while
ShadowImage for Mainframe pair and
Compatible FlashCopy® V2 Mirror pair are
defined in the specified volume, the Check
Paths operation is rejected with a message “605
2518”. If ShadowImage for Mainframe pair and
Compatible FlashCopy® V2 Mirror pair are
defined in the specified volume, do not perform
Check Paths and wait until the display is
automatically changed.
