6. Disk Configuration
This chapter covers these topics:
6.1 Disk Specifications
6.2 IRIS Workstation Disk Configuration
6.3 IRIS Terminal Disk Configuration
The tables in Section 6.1 should be used as reference material for the
procedures described later in the chapter. Table 6-1 shows the default division
of all the available disks into partitions. This chapter explains how to change
partition size.
The disks on the IRIS 3010 and 3020 are called
md
; the disks on the IRIS 3030 are
si
. To find out what brand of disk you have on your workstation, issue the
sgilabel command:
IRIS 3010/3020:
sgilabel md0
IRIS 3030:
sgilabel si0
A first disk is disk zero; a second disk is disk 1. Disks are divided into a
number of partitions depending on the brand and size; the partitions are
labeled with lower-case letters a through g . The two formatter/exerciser
programs, mdfex and sifex , correspond to the two types of disk,
md
and
si
.
These programs enable you to change the size of the swap partition on your
disk.
The commands
mkfs (1M) and labelit (1M) enable you to configure a second disk.
The basic steps in this procedure are making file systems, labeling them, and
modifying configuration files so that the file systems are mounted and checked
by fsck (1).
