3. Creating an HDLM Environment

21. Verify that the settings for the parent device (fscsin) 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

22. Enable the defined parent device (fscsin).

# cfgmgr -l fscsi

23. Repeat steps 19 to 22 for each parent device (fscsin) being used.

24. 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

25. 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.

26. Make sure that hdisks are available:

# lsdev -Cc disk
