Multipathing enable: migrate from netapp to hds

Question

Our Solaris 9 boxes have been using Netapp San (Brocade switch)
We have purchased HDS SAN systems (the Virtual Storage Platform)
which also use Brocade 5100 switch
Have tested on test server by switching from the old Netapp San to the new HDS San
and see the disks okay.
But the old SAN have been using mpxio for the multipathing
So could someone outline the procedure to enable multipathing for the
new HDS San
(Presumably the mpxio won;t work and have to be disabled first)
BTW, the HBA cards are Emulex L10000
Thanks in advance

Answer 1

Thanks Nik
Yes, the file ssd.conf seems like what you said,
only define some netapp specifics & timeouts
(I'll list them at the bottom). I think I will simply
revert to the original ssd.conf (which I have a backup) before configuring it for HDS
Now from my understanding, the following steps
are required to enable mpxio to use the HDS San:
(Pls correct me if there're some steps not
required. I've just found this from someone's blog, but it is for solaris10)
1. Add a line to kernel/drv/fp.conf
mpxio-disable="no"
2. Edit the scsi_vhci.conf
to remove the Netapp related entries and
add those which are HDS specific (as you told
me in your first response)
3. Do the command
stmsboot -e
(Note since my solaris is 9 , so I cannot
do the better syntax stmsboot -D fp -e But my box
is a sunfire 245 whose internal disk should not
be fibre and so won't matter ??? True ?)
which will reboot for me and enable mpxio
4. Do another boot by
touch /reconfigure
init 6
I have questions about 1 & 3 which I hope
you could clarify for me
For 1, I notice that in my present working
multipathing with the Netapp san , I do
not even have the line mpxio-disable="no".
, yet it is still working
For 3, the manual says stmsboot -e
does 3 things
(a) add the line
mpxio-disable="no" to fp.conf
(b) make things right for the vfstab file
(c) enable mpxio
If so, then is step 1 really redundant ?
BTW, I know mpxio works only of my Solaris
has certain patches installed. How do I find out
which the patch pre-requisites?
P.S. Here are the added lines in my ssd.conf
(for Netapp)
throttle_max=64
not_ready_retries=30
busy_retries=30
reset_retries=30
throttle_min=8
