38 Functional and operational characteristics
Description
page allocation is not provided at a time when the HDP pool is
full. (Not to set in the case of Read request.)
Mode 729 = OFF (default):
Not to set the Protect attribute for the target DP-VOL using Data
Ret, when any write operation is requested to the area where the
page allocation is not provided at a time when HDP pool is full.
Notes:
1. This SOM is applied when:
- The threshold of pool is high (e.g., 95%) and the pool may
be full.
- File system is used.
- Data Retention is installed.
2. Since the Protect attribute is set for V-VOL, the Read operation
cannot be allowed as well.
3. When Data Retention is not installed, the desired effect is not
achieved.
4. Protect attribute can be released from the Data Retention
window of Remote Web Console after releasing the full status
of the pool by adding a Pool-VOL.
This option enables to suspend Volume Migration or Quick Restore
operation during LDEV-related maintenance.
Mode 733 = ON:
Auto LUN V2 or Quick Restore operation during LDEV-related
maintenance is not suspended
Mode 733 = OFF (default):
Auto LUN V2 or Quick Restore operation during LDEV-related
maintenance is suspended
Notes:
1. This option should be applied when Auto LUN V2or Quick
Restore operation can be suspended during LDEV-related
maintenance.
2. Set mode 733 to ON if you want to perform any LDEV-related
maintenance activities and you do not want these operations to
fail when Volume Migration or Quick Restore is active.
3. This option is recommended as functional improvement to
avoid maintenance failures. In SOM e cases of a failure in
LDEV-related maintenance without setting the option, Storage
Navigator operations may be unavailable.
4. There is the potential for LDEV-related maintenance activities
to fail when Auto LUN V2 and Quick Restore is active without
setting the option.
When exceeding the pool threshold, the SIM is reported as
follows:
Mode 734 = ON: The SIM is reported at the time when exceeding
the pool threshold. If the pool usage rate continues to exceed the
pool threshold, the SIM is repeatedly reported every eight (8)
hours. Once the pool usage rate falls below the pool threshold,
and then exceeds again, the SIM is reported.
Mode 734 = OFF (default): The SIM is reported at the time when
exceeding the pool threshold. The SIM is not reported while the
pool usage rate continues to exceed the pool threshold. Once
the pool usage rate falls below the pool threshold and then
exceeds again, the SIM is reported.
