.
Make sure that the boot disk is in a multi-path configuration:
# lspath -l hdisk10 -s available
Available hdisk10 fscsi0
Available hdisk10 fscsi1
...
The following procedure assumes that hdisk10 is recognized as a boot
disk:
17
.
Check the current boot disk list:
# bootlist -m normal -o
hdisk10 blv=hd5
hdisk0 blv=hd5
hdisk1 blv=hd5
...
18
.
Specify boot disks that are suitable for your host environment:
# bootlist -m normal hdisk10 hdisk0 hdisk1
19
.
Make sure that the number of configured boot disks is the same as the
number of paths that you checked in step 15:
# bootlist -m normal -o
hdisk10 blv=hd5
hdisk10 blv=hd5
hdisk0 blv=hd5
hdisk1 blv=hd5
...
If the hosts and storage systems are connected by a Fibre Channel
switch, perform steps 19 to 23. If the hosts and storage systems are not
connected by a Fibre Channel switch, go to step 24.

.
Finish defining the parent device (fscsin).
# rmdev -l fscsin -R
Note that you can use the following command to check the parent device:
# lsdev -C -l hdisk-name -F 'parent'
21
.
Change the fc_err_recov setting of the parent device (fscsin) to
fast_fail.
# chdev -l fscsin -a fc_err_recov=fast_fail
22
.
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
23
.
Enable the defined parent device (fscsin).
# cfgmgr -l fscsin
24
.
Repeat steps 19 to 22 for each parent device (fscsin) being used.
