NAME

rasize − report on MSCP disk partition sizes

SYNTAX

rasize

DESCRIPTION

The RA disk driver supports a variety of MSCP disks. The partition sizes for MSCP disks are not known in advance, because this information is read from the disk when the driver brings it on-line.

The rasize command reports the following information about MSCP disks:

1. The controller type (UDA50, RQDX1, KLESI, or RUX1) and micro-code revision of each MSCP disk controller on the system.

2. The status of each MSCP disk unit, NED for a non-existent drive or the disk type (RC25, RA60, RA80, RA81, RX50, RD51 or RD52) if the unit exists. A disk is non-existent until it becomes available to the driver, this occurs on the first access of the disk unit.

3. Which of the eight possible disk partitions may be used, when creating file systems.

4. The absolute maximum sized file system that may be created on each available disk partition. This size number should be supplied to the /etc/mkfs command when making file systems on MSCP disk partitions.

DIAGNOSTICS

May cause a “drive offline” message on the console terminal if the RX50 drives are not online.
