36 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Verifying the device files and drivers

The device files for new devices are usually created automatically during

HP-UX startup. Each device must have a block-type device file in the

/dev/dsk directory and a character-type device file in the /dev/rdsk

directory.

However, some HP-compatible systems do not create the device files

automatically. If verification shows that the device files were not created,

follow the instructions in

“Creating the device files” (page 38) to create the

device files manually.

This procedure verifies both types of device files.

To verify that the device files for the disk array devices were created:

1. Display the block-type device files in the /dev/dsk directory using the

ls –l command with the output piped to more. Verify there is one

block-type device file for each disk array device.

Example

# ls –l /dev/dsk | more

Total 0

brw-r - - - - - 1 bin sys 28 0x006000 Dec 6 15:08

c6t0d0

brw-r - - - - - 1 bin sys 280 0x06100 Dec 6 15:08

c6t0d1

2. Verify that the block-type device file name for each device is correct.

3. Display the character-type device files in the /dev/rdsk directory using

the ls –l command with the output piped to more. Verify that there is

one character-type device file for each disk array device.
