How to set/cancel RAID level
Set the RAID level for each RAID configuration unit when formatting it so that the unit can perform write/read to the
RAID configuration unit based on the RAID level.
≥ You can specify the RAID level to format magazine on the unit or application.
To specify the RAID level with the unit, select "Configure"
For the settings of the RAID level from the application, refer to the user manual for the application.
` Even if the RAID level is specified in the unit, the RAID level settings in the application take precedence.
` If a RAID level has been specified through an application, the RAID level cannot be specified on the unit.
≥ To verify the RAID level settings, select "Monitor"
interface. ( 31)
≥ When changing the application, the RAID level for formatting the RAID configuration unit should be reset so that
the RAID level can be specified on the unit. Select "Configure"
Web interface to execute. (
Note
≥ Do not execute "Reset RAID Setting" except when it is required. If it is executed when it is not needed, the
RAID level that has been set by the application and the RAID level of magazine may not be the same
depending on the application.
≥ Decrease of Redundancy
` When the write or read performance is poor due to failure, i.e. the redundancy is decreased, prompt solution
of problems is recommended.
` When you perform writing with the RAID 5 and the number of drive failure is 1, or RAID 6 and the number of
drive failure is 1 or 2, the RAID configuration unit is written in the lower redundancy status. Although you
have resolved the problem, the written part of RAID configuration unit is still lower redundancy. We
recommend that you copy the contents to another magazine after resolving the problem.
