3. Creating an HDLM Environment

15. Change the

fc_err_recov

setting of the parent device (

fscsi

n) to

fast_fail

.


# chdev -l fscsin -a fc_err_recov=fast_fail

16. Verify that the settings for the parent device (

fscsi

n) are enabled.

Also, verify that the

fc_err_recov

setting has been changed to

fast_fail.


# lsattr -El fscsin
fc_err_recov fast_fail FC Fabric Event Error RECOVERY Policy
TRUE

17. Repeat steps 14 to 16 for each parent device (

fscsi

n) being used.

18. Enable the defined parent device (

fscsi

n).


# cfgmgr

19. Execute the

chdev

command, as required, to change the attributes of the hdisk:


# chdev -l

hdisk-name

-a queue_depth=8 -a rw_timeout=60

20. Execute one of the following commands, as required, to add

/usr/

DynamicLinkManager/bin

to the

PATH

environment variable.

When using a Bourne shell or Korn shell:

# PATH=$PATH:/usr/DynamicLinkManager/bin

# export PATH

When using a C shell:

# set path=( $path /usr/DynamicLinkManager/bin )


To simplify command execution, you can temporarily add the

PATH

environment

variable. To execute HDLM commands or the HDLM utility without setting the

PATH

environment variable, specify an absolute path to execute the commands.

21. Make sure that hdisks are available:

# lsdev -Cc disk
hdisk0 Available 1S-08-00-8,0 16 Bit LVD SCSI Disk Drive
hdisk1 Available 1S-08-00-9,0 16 Bit LVD SCSI Disk Drive
hdisk2 Available 1S-08-00-10,0 16 Bit LVD SCSI Disk Drive
