3. Creating an HDLM Environment
92
The following procedure assumes that hdisk10 is recognized as a boot disk:
16. Check the current boot disk list:
# bootlist -m normal -o
hdisk10 blv=hd5
hdisk0 blv=hd5
hdisk1 blv=hd5
...
17. Specify boot disks that are suitable for your host environment:
# bootlist -m normal hdisk10 hdisk0 hdisk1
18. 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.
19. 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'
20. Change the fc_err_recov setting of the parent device (fscsin) to
fast_fail.
# chdev -l fscsin -a fc_err_recov=fast_fail
