High Availability Disk Array (Nike)

With MPE/iX 6.0 there is support for 9 GB and 18 GB disk drives. Please note the following restrictions.

The 9 GB and 18 GB drives are supported as RAID 1 only (that is, NOT as RAID 5, since this would exceed the 18 GB volume limit currently in effect.)

The 9 GB and 18 GB drives may not be used as the boot device; however, that is not recommended.




	NOTE: This is NOT recommended because only 4 GB is allowed by IODC in the current implementation. The 5 GB and 14 GB difference would be unusable capacity. The release marks the space beyond 4 GB as unusable so the OS updates can occur without violating the 4 GB limitation.

Flare code 9.55.01 (or later) and PROM code 0173 (or later) are required for the array controller.
Support is for Model 20 Differential only.
HPC2300WD is the SYSGEN ID.

The following table shows the supported configurations:
