Ver ify ing host recognition of disk array devices

Use the scu show edt command at the UNIX p rompt to see the list of new disk array devices.

The device ﬁles are created automatically in Tru64 UNIX during system startup. Device ﬁles are created

for each logical unit.

1. Verifythecharacter-typedeviceﬁles have been automatically created:

Example — Tr

u64 v5.1B

# file /dev/rdisk/dsk*

2. Verify the

block-type device ﬁles have been automatically created:

Example — Tru64 v5.1B

# file /dev/disk/dsk*

Conﬁgure disk devices

Conﬁgure disks in the disk array using the same procedure for conﬁguring any new disk on the host.

This includes the following procedures:

1. Writing the partition labels

2. Creating the ﬁ le systems

3. Creating mount directories

4. Mounting the ﬁle systems

5. Verifying the ﬁle systems

6. Setting and verifying automatic mounting at bootup

7. Checking path failover

Creating scripts to conﬁgure all devices at once may save you considerable time. Refer to Tru64 UNIX

S ystem Administr ation for detailed procedures.

Wri

ting the partition labels

Use

the disklabel command to label the partition for each logical unit. Partition c spe ciﬁes the entire area

in t

he logical u nit. Check that no errors are found in the partition set tings after the labeling.

You can edit the disk partition size using the disklabel command with option –e. When the disklabel

–e command is executed, the vi editor for the environment in which you a re working starts up. After

completing the editing, save the ﬁle and execute the disklabel command again; the par tition setting

is renewed.
