Hi all,
Here are the specifics. CPQ DL360 - RAID1 (36GB Drives) with
Solaris 8 01/01.
Using the same premise as Solaris on SPARC, you can not recover the
operating system without an alternate path restore. On Solaris on SPARC I
generally install the core OS and the NBU agent on an alternate disk...then
do an Alternate Path restore..i.e. From / to /a/. This works. However on
Solaris for Intel I have come into some issues. Basically I install the
core OS with the NBU agent on slice 7 of the disk....and also install it as
per normal on the other slices.
Slices 0-6 are used for the production instance and my thoughts are...hey if
we need to recover...we just change the boothpath and boot from slice 7 and
then restore slices 0-6. I alluded to this in one of my previous postings
about installing two instances of Solaris on a single drive.
Darren Dunham mentioned that I would have some strange behaviour (he
was right). Part of me wishes I could just roll this out on SPARC but as
with most people I am on a budget crunch. I have a feeling it has something
to do with the bootblk. I have tried setting this up with a specific
x86boot partition and without that boot partition. I have used installboot
to install the bootblk. When all said and done I always get the same
result. Can't boot from /pci@0,0/pcie11,4040@1/sd@0,0:a - Slice not
allocated. If I boot back
to slice 7 I can confirm that these are the device names of the disk in
question.
I am hoping to have a recovery solution in place for this system in
early Jan so I can roll out a production syslog server. Any suggestions you
can provide would be greatly appreciated.
Thanks and will summarize.
Marco.
