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
