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.
