How to set/cancel RAID level
Set the RAID level for each magazine when formatting it so that the unit can perform write/read to the magazine
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 "Config"/"Configure" "Set RAID Level" on the control panel or the
Web interface. ( 56, 94)
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" "Drive" "RAID / Encrypt" or "Monitor" "Drive" "RAID
Level" on the control panel or the Web interface. ( 40, 76)
≥ When changing the application, the RAID level for formatting the magazine should be reset so that the RAID level
can be specified on the unit. Select "Configure" "Set RAID Level" "Reset RAID Setting" on the Web interface
to execute. ( 94)
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 magazine is written in the lower redundancy status. Although you have resolved the
problem, the written part of magazine is still lower redundancy. We recommend that you copy the contents of
magazine to another magazine after resolving the problem.
