ICKDSF support of the RAMAC Array family
The AIX® Array family consists of the following devices:
- RAMAC Array Subsystem (9394)
- RAMAC Array DASD (9391)
- RAMAC Virtual Array (9393)
- RAMAC Scalable Array (9396)
- RAMAC Electronic Array (9397)
The characteristics of the physical devices that make up the RAMAC Array Family do not require use of the ICKDSF commands that perform installation, media maintenance and problem determination functions. These functions are currently part of the following commands:
- INSTALL1
- ANALYZE
- INSPECT
- REVAL
ICKDSF supports the command and parameter combinations of these commands whenever possible. For those command and parameter combinations that are not supported on the RAMAC Array DASD and the RAMAC Array Subsystem, ICKDSF detects the ones which cannot execute and posts an error condition.
For example, an INSPECT PRESERVE CHECK(1) is not supported on the RAMAC Array DASD. A message is issued indicating that the function is not supported for the device.
However, an INSPECT PRESERVE CHECK(1) on the RAMAC Array Subsystem issues commands to preserve data and surface check the track. No data check conditions will ever be indicated, since media maintenance is done by the subsystem.
When you use the following commands in support of devices emulated by the RAMAC products, they support the emulated device in the same way they support the native device.
- INIT NOVALIDATE (minimal init)
- CPVOLUME
- AIXVOL
- BUILDIX
- PPRCOPY
- REFORMAT
