Mode 733 = ON:
Volume Migration or Quick Restore operation during LDEV-
related maintenance is not suspended
Mode 733 = OFF:
Volume Migration or Quick Restore operation during LDEV-
related maintenance is suspended.
Notes:
1. (USP V/VM) This option is recommended as functional
improvement to avoid maintenance failures. In some cases
of a failure in LDEV-related maintenance without setting the
option, Storage Navigator operations may be unavailable.
2. (USP V/VM) There is the potential for LDEV-related
maintenance activities to fail when Volume Migration and
Quick Restore is active without setting the option.
3. Note that behavior when the mode is set to ON and OFF
is reversed between USP V/VM and VSP and later/HUS VM
and later.
4. (USP V/VM) This option should be applied when Volume
Migration or Quick Restore operation can be suspended
during LDEV-related maintenance.
5. (USP V/VM) If virtual volume capacity expansion
operation conflicts with Volume Migration or Quick Restore
operation, the virtual volume capacity expansion operation
may fail.
6. (VSP and later/HUS VM and later) This mode should be
applied to perform Volume Migration or Quick Restore
during maintenance operation.
7. (VSP and later/HUS VM and later) Set mode 733 to ON if
you want to prioritize the Volume Migration or Quick Restore
operation over maintenance activities. In this case,
maintenance activities may fail when the Volume Migration
or Quick Restore operation works during the maintenance
activities.
8. (VSP and later/HUS VM and later) An LDEV-related
maintenance operation such as LDEV installation/removal
may fail when Volume Migration or Quick Restore takes
place.
734
When exceeding the pool threshold, the SIM is reported as
follows.
Mode 734 = ON:
A SIM is reported at the time when the pool usage rate
exceeds the pool threshold (warning, system, or depletion).
Once the pool usage rate falls below the pool threshold, and
then exceeds again, the SIM is reported again. If the pool
usage rate continues to exceed the warning threshold and
the depletion threshold, the SIM (SIM-RC625000) is
repeatedly reported every eight (8) hours until the pool
usage rate falls below the depletion threshold.
