RA4000/RA4100 Array disk grouping for a PDC/O1000 cluster
Using the Compaq Array Configuration Utility, group the RA4000/RA4100
Array disk drives into RAID disk arrays at specific RAID levels. This example
shows four disk drives grouped into one RAID disk array at RAID level 5. It
also shows two RAID level 1 disk arrays containing two disk drives each.
A logical drive is what you see labeled as Disk 1, Disk 2, and so on, from the
Disk Management utility. For information about RAID disk arrays and logical
drives, refer to the information on drive arrays in the
Compaq StorageWorks
RAID Array 4000 User Guide
or the C
ompaq StorageWorks RAID Array 4100
User Guide
