Step 5. Replace LUN 0 LUN 0 was created solely to allow the host to communicate with the disk array when it is first powered on. It should be replaced with a usable LUN. If not replaced, a substantial amount of storage will be wasted. To replace LUN 0, type: amcfg -R :0 -d ,..... -r For example, the following command replaces LUN 0 with a RAID 0/1 LUN using four disks: amcfg -R A:0 -d 1:0,2:0,3:0,4:0 -r 1 • For a complete explanation of the command syntax and parameters, refer to the amcfg man page, or see "Replacing a LUN" on page 294. Step 6. Disable WCE On All Disks For optimum data protection, WCE (Write Cache Enable) should be disabled on all disks in the array. To disable WCE on all disks, type: amutil -w Note To ensure optimum protection against data loss, it is recommended that Write Cache Enable be disabled on all disks in the array. Disabling disk WCE will impact disk array performance. However, it reduces the potential for data loss during a power loss. Step 7. Set Disk Array Time and Date The disk array maintains its own time and date internally. These values are used to write time stamps on log entries. The disk array settings should be synchronized with the time 218 Configuring the Disk Array
