Note
When RAID Consolidation is performed in ETERNUS6000 the RAIDGroup response time will not be displayed.
LogicalVolume(LUN) and RAIDGroup performance information including LogicalVolume, created by LUN Concatenation in the ETERNUS8000 and ETERNUS4000 (except models 80 and 100) that firmware versions are before V11L40, will not be displayed.
Performance information about the ETERNUS disk storage system main frame volume and MVV/SDV are not supported, and performance information values for RAIDGroup cannot be guaranteed.
On ETERNUS6000 devices, CA performance information relates to the FC-CA or FC-RA port. Furthermore, performance information obtained during the execution of REC and ROPC is displayed as Write performance information, regardless of whether FC-RA port is set up on the Initiator side or the Target side.
ETERNUS8000 and ETERNUS4000 (except models 80 and 100) CA performance information displays FC-CA port or FC-RA port performance information. Performance information during the execution of REC and ROPC will be displayed as follows.
It will be displayed as Read performance information, if FC-RA port is set on the Initiator.
It will be displayed as Write performance information, if FC-RA port is set on the Target.
The performance information for the number of active disks can be managed by setting to perf.conf file. For the settings, refer to "C.4 perf.conf Parameter".
