DS300f G2 Series User Manual227creatInG a DISk array or loGIcal DrIveWhy can’t I see all RAID Levels in RAID Level drop-down menu?The selection of RAID Levels shown depends on number of physical drives available to the controller. For example,if there are only two physical drives, then you cannot see RAID 10, which requires four physical drives or RAID 50that requires at least six. See "RAID Levels" on page .Why can’t I create more than one logical drive on my disk array?If your logical drive takes up the entire capacity of the disk array, there is no room for another logical drive. Backupyour important data, then delete the existing logical drive and create multiple smaller logical drives on the disk ar-ray. See “Deleting a Logical Drive” on page 98 and 139 and “Creating a Logical Drive Manually” on page 97.DISk array DeGraDeDAccording to ASUS Storage Management, my disk array is degraded. What am I supposed to do?If the Auto Rebuild option is enabled and a hot spare drive is available, your disk array begins rebuilding automati-cally. Also see "Disk Array Degraded / Logical Drive Critical" on page When an disk array becomes degraded, can I still access the data on it?Yes, but reads and writes take longer while rebuilding is in progress.DeletInG a DISk array or loGIcal DrIveWhy can’t I select Delete Disk Array or Delete Logical Drive?You must have Power or Super User Rights to delete a disk array or logical drive.

You must clear (erase) the Re-serve Sector of the replacement disk drive before the system can rebuild to it. “Clearing a Stale or a PFA Condition”on page 130.mIGratInG a DISk arrayWhen I try to migrate a disk array from one RAID level to another, why doesn’t the controller let me doit?Most RAID levels have a minimum and maximum number of physical drives. Be sure you have the correct number ofdrives available for the target disk array. See "RAID Levels" on page and "RAID Level Migration" on page .I want to add two more drives to my RAID 1 disk array. Why won’t the controller let me migrate it?A RAID 1 disk array uses only two disk drives. In this case, you can add two physical drives, then convert to a RAID10 disk array. Most RAID levels have a minimum and maximum number of disk drives. See "RAID Levels" on page.meDIa Patrol anD PDmMedia Patrol and PDM are enabled on my system. But they never report anything.This is a good sign. Media Patrol and PDM operate transparently until they find a problem on a physical drive.
