168 Software Installation and User’s Guide
ICP RAID Navigator
Tagged Queues
This feature enables modern hard disk drives to receive several commands at one time and
then process them in an optimized order. A few, mainly older drives, do not support this
feature. You can change the tagged queues setting for a hard disk in the SCSI parameters /
Initialize menu.
SCSI Read Cache / SCSI Write Cache
These settings enable or disable the write and read caches of the hard disks. Turning these
caches OFF degrades the performance of the hard disk. You can change the cache settings
of a drive in the SCSI parameters / Initialize menu.
11.4.3.2 Check Surface
Warning: This option destroys all data on the hard disk.
This option checks the surfaces of the selected hard disk media. The ICP RAID controller
writes and reads certain data patterns and checks them for correctness.
After you choose the Check Surface option, ICP RAID Navigator displays a warning that
performing this command will destroy all data. Press <Y> to do a surface check or press
<N> to cancel. If you choose to do the surface check, ICPCON displays a progress
information bar with the elapsed time and estimated time of completion. You can interrupt
the surface check by clicking the Cancel button.
11.4.3.3 Deinitialize Disk
De-initializing a physical drive removes the initialization sectors. The physical drive
cannot be a member of a logical drive once it is deinitialized.
11.4.3.4 Lock Disk / Unlock Disk
With this function you can lock or unlock a removable drive containing a removable
medium. If the physical drive is locked, the medium cannot be ejected with the eject
button while the system is running.
