The scenario is 2 X 9GB LUNS from Hitachi SAN using Hitachi MPIO Disk USP (Fibre)to presnet hdisk0 and hdisk1 for rootvg.
(Note: I know this over kill to mirror rootvg at the OS level when the Hitachi SAN is protecting rootvg using RAID5, but noticed somthing strange from the output of the bootlist command.)
Procedure for mirroring rootvg:
[b]host1:/# mirrorvg -m -c 2 rootvg hdisk1[/b]
0516-1124 mirrorvg: Quorum requirement turned off, reboot system for this
to take effect for rootvg.
0516-1126 mirrorvg: rootvg successfully mirrored, user should perform
bosboot of system to initialize boot records. Then, user must modify
bootlist to include: hdisk0 hdisk1.
[b]host1:/# bosboot -a -d /dev/hdisk1[/b]
bosboot: Boot image is 30447 512 byte blocks.
host1:/#
[b]host1:/# bootlist -om normal hdisk0 hdisk1[/b]
hdisk0 blv=hd5
hdisk0 blv=hd5
hdisk0 blv=hd5
hdisk0 blv=hd5
hdisk0 blv=hd5
host1:/#
QUESTIONS:
1. Why is "hdisk1 blv=hd5" missing from the bootlist command output?
2. Why is there 5 entries for hdisk0? I'm assuming it's because of the number of path's to the external storage. If number of paths is the case, there should be 6 entries for hdisk0 becasue there are 6 paths to the Hitachi storage.
3. Is there a limitation to the bootlist command?
COMMENTS:
1. I can list hdisk1 before hdisk0 on the bootlist command and hdisk1 is now the output 5 times and no listing for hdisk0.
2. I swap the hdisk's in the bootlist command and reboot from each disk without issue.
Any Ideas????
