146J.4.6.1 Menu Advanced Setup: Configure Array Drives, Change Drive NameThis command allows you to change the name of an Array Drive. The name serves to iden-tify an Array Drive in ICPCON or ICP RAID Navigator. This can be very helpful for configura-tions where several Host Drives of various types are operated by a single controller.J.4.6.2 Menu Advanced Setup: Configure Array Drives, Expand Array DriveThe Expand Array Drive option which is also available withICP RAID Navigator, contains three major functions:1. Conversion of a free space on the Logical Drives into aseparate Host Drive2. Migration of the RAID level of a given Array DriveRAID 0 -> RAID 4 and vice versaRAID 0 -> RAID 5 and vice versa3. Expansion of the capacity of a given Array DriveTo initiate a migration or expansion with a RAID 4/5 Array Drive, the state must be ready.The data on the Array Drive remain intact and are not affected by the expansion.The additional capacity is introduced as new Host Drive. If a Logical Drive fails during theexpansion, the expansion process continues until the expansion is finished. The ArrayDrive changes into the fail state.J.4.6.3 Menu Advanced Setup: Configure Array Drives, Add RAID 1 ComponentIn certain "emergency" cases this is a very powerful and helpful option. This function allowsyou to add to a Logical Drive which is member of an Array Drive, another Logical Drive as amirror drive (RAID-1).Example: You have configured an Array Drive with 4 Logical Drives. One Logical Drive hasfailed and the Array Drive went into the fail state. Another failure would cause data loss.Unfortunately, you find another Logical Drive, which is shortly before failing (e.g., you heara strange noise from it, or it's grown defect counter explodes). If you now initiate a hot plugit is very likely that this critical Logical Drive will also fail. This would result in a disaster. Toavoid that problem, you can mirror in a first step a new good Logical Drive to the criticalone. When the copying is finished you remove the critical Logical Drive and then carry out ahot plug procedure. You can also use this function to mirror RAID 4/5 Array DrivesRAID 5+1, RAID 4+1)J.4.6.4 Menu Advanced Setup: Configure Array Drives, Replace Array ComponentIf a Logical Drive of an Array Drive without a Hot Fix drive should fail (or is very likely to fail,soon), you should replace the defective hard disk with a new one as soon as possible be-cause the Array Drive is without redundancy. The replacement Logical Drive has to have atleast the same capacity as the failed one. The replacement is carried out either withICPCON or ICP RAID Navigator. After having installed the replacement hard disk as a newLogical Drive, you can add it to the Array Drive. After selecting the Logical Drive whichneeds to be exchanged, ICPCON offers a list of existing Logical Drives which can be used asreplacement units. The Array Drive's state is changing into rebuild and the missing data isautomatically reconstructed on the new Logical Drive.J.4.6.5 Menu Advanced Setup: Configure Array Drives, Remove RAID 1 ComponentThis option corresponds with the Add RAID-1 Component option. It allows you to remove apreviously configured RAID-1 combination.
