Table 6-2: Disk Storage Requirements
6.2 IRIS Workstation Disk Configuration
The three subsections below describe these procedures:
• Changing the swap partition size on an IRIS 3020
• Changing the swap partition size on an IRIS 3030
• Configuring a second disk on an IRIS 3020/3030
If you have an IRIS 3010, see Section 6.3.
On an IRIS 3020 or 3030, disk zero is divided into three partitions: the root
partition, which contains the root file system; the swap partition, which is used
by U
nix
for paging; and the user partition, which contains the /usr file system.
On an IRIS 3020, the root partition is device md0a , the swap partition is md0b ,
and the user partition is md0c . On an IRIS 3030 the root partition is device
si0a , the swap partition is si0b , and the user partition is si0f .
The size of the swap partition determines the maximum amount of virtual
memory that can be used. At any instant in time, the sum of the sizes of all
the processes known to U
nix
cannot exceed the size of the swap partition.
If the simultaneous processes running on your workstation require more space
on the swap partition, you can make it larger at the expense of some of the free
space in the user file system. You can increase the space available for user files
by reducing the swap partition size, but this reduces the total of the process
sizes that can exist simultaneously on the system.
