Full Installation on Compaq Tru64 UNIX

5.1 Preparing for RTR Installation on Compaq Tru64 UNIX

The display indicates that

/usr

(mounted to

/dev/rd0g

) is the only mount

point that affects where RTR ﬁles will reside; the system has only one local

disk drive, and the

/usr/lib

and ﬁle system resides in the

partition of the

disk on that drive.

To check the total space and the free space for the directories where RTR will

reside, enter the

command. Given the previous display of the

/etc/fstab

ﬁle, which shows that only

/usr

is a mount point, you need to check free space

only in the

/usr

ﬁle system. For example:

# df /usr

Filesystem Total kbytes kbytes %

node kbytes used free used Mounted on

/dev/rd0g 122598 54447 55892 49% /usr

This display shows that there are 55,892 Kbytes free. This free space must

accommodate the subset requirements listed in Table 5–1, RTR Subset Size

(Kilobytes Required).

On systems where

/usr/lib

and

/usr/man

are mounted to different devices

from

/usr

, enter the following command:

# df /usr/lib /usr/man

In this case, you compare space required for RTR ﬁles in

/usr/lib

to the free

space displayed in the ﬁrst line of the

output list, and compare the space

required for RTR ﬁles in

/usr/man

to the free space displayed in the second

line of that list.

5.1.4.5.2 Increasing Disk Space by Using Alternative Disks The RTR

installation procedure creates the following directory and loads ﬁles into

subordinate directories:

/usr/opt/RTR400

If the

/usr/opt/RTR400

directory in the previous path does not exist, the

installation procedure creates it.

If the

RTR400

directory does exist, the installation procedure uses it.

If you ﬁnd that there is insufﬁcient disk space for the RTR subsets and you

know that you have additional space on alternative disks or disk partitions for

your system, perform the following steps before installing RTR:

1. Log in as superuser.

2. Create the directory

/usr/lib/RTR400
