tolerant RAID level when able, and creates a hot spare drive for drive failure
protection. The number of logical drives created is dependent on the total
number of physical drives discovered.
The administrator can edit the following parameters within the
autoconfig.dat file:
• Total number of physical disk drives available.
• Number of physical disk drives in each logical drive.
• RAID level (RAID 0, RAID 1, RAID 3, RAID 5, RAID 0+1, and
JBOD).
• Write cache policy: write-through (WT) or write-back (WB).
• Desired usable logical drive size, in MB.
• Number of hot spare drives.
Multipliers can be added as part of the logical drive configuration to indicate
replication of the logical drive definition on the same set of drives.
If the “autoconfig.dat” file is not found, the Global Array Manager will
notify the administrator with an error window, and then ask if the
administrator would like the Global Array Manger to create an example file.
The example file will be the default file created at the time of the client
installation.
