SUMMARY: V880 boot-device paths for dual-pathed mirrored internal FC devices.

No replies, but with a little time and testing it was as easy as I
expected. I dropped to ok and ran:

nvalias bootdisk1
/pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w500000e0102a7d01,0:a
nvalias bootdisk2
/pci@9,600000/pci@1/SUNW,qlc@4/fp@0,0/disk@w500000e0102a7d02,0:a
nvalias bootmirror1
/pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w500000e0102ea991,0:a
nvalias bootmirror2
/pci@9,600000/pci@1/SUNW,qlc@4/fp@0,0/disk@w500000e0102ea992,0:a
setenv boot-device rootdisk1 rootdisk2 rootmirror1 rootmirror2
setenv use-nvramrc? true
set auto-boot? false
reset-all

I then proceeded to do a boot/init0 with each alias to test that the
system could use all 4 paths to both disks to boot.

Once finished I dropped to ok again and ran:
set auto-boot? true
reset-all

Hopefully this will help anyone else that has a v880 or v890 with two
loops on their internal FC backplane.

Subject: V880 boot-device paths for dual-pathed mirrored internal FC
devices.

All,

I have a Solaris 9 V880 with Multipathed internal FC drives and two of
these drives make up my root mirror. I'd like to set my boot-device to
include all 4 paths to the two drives but I'd like to validate the
correct syntax to do this. Documents that I have seen that cover this do
not deal with FC drives.

What I do know concerning the two disks:

    Class                       primary
    State                       ONLINE

And the current boot-device setting is:
boot-device = /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w500000e0102a7d01,0:a
              /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w500000e0102a7d01,0:d
(Not sure why the above one is in here; if :d refers to partition 3
that's a swap partition)
              /pci@8,700000/scsi@4/disk@0,0:d (Not sure why the above
one is in here; there is no scsi@4 directory listed under OBP)
              disk net

I'm guessing my new boot-device settings should be:
/pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w500000e0102a7d01,0:a
/pci@9,600000/pci@1/SUNW,qlc@4/fp@0,0/disk@w500000e0102a7d02,0:a
/pci@8,600000/SUNW,qlc@2/fp@0,0/disk@w500000e0102ea991,0:a
/pci@9,600000/pci@1/SUNW,qlc@4/fp@0,0/disk@w500000e0102ea992,0:a

If anyone has done this and can validate my thinking I'd be grateful.
And if anyone can explain why the suspected swap partition would be
listed as a boot-device that'd bee cool too. ;)
