DSF - Including a path

sexta-feira, 13 de julho de 2012

The bellow example show how you can use the mksf command to manually create device files with default names, your own device file name, and custom device file corresponding to certain device options.

First of all check the disks and get the  HW address:
# ioscan -fnNC disk
(Example output bellow)
disk 344 64000/0xfa00/0x8c esdisk CLAIMED DEVICE DGC CX500WDR5
/dev/disk/disk344 /dev/rdisk/disk344

Insert the unique hardware path (-H option) and the path name as you need:
# mksf -C disk -H 64000/0xfa00/0x8c -r /dev/erptrn/asm/db50

Run the ioscan again to check the path for your disk:
# ioscan -m dsf

Using this option os ioscan command you can see all paths for your disks (persistent and legacy DSF)

This tip is useful for someone who aren't "familiar" with HP-UX 11v3.
# ioscan -m dsf
Persistent DSF           Legacy DSF(s)
