I have a question about using EMC's powerpath with MC/Serviceguard.
The EMC arrays are installed, cabled, etc, and Powerpath shows the LUNs with
different alternate paths to the disks (c11t0d1, c12t0d1, c13tod1, c14t0d1
for ex.). Each LUN has four different devices pointing to it.
I do see that 2 of each of the four devices point to a different SP
(Service Processor) on the EMC side.
HP-UX sees the devices, etc. and can talk to them.
When I am building the volume group(s), how to I tell Serviceguard about the
alternate paths or DO IT NEED TO? Powerpath itself is supposed to handle
pathing to the devices (I believe).
Do I need to do the vgextend to include the other device files? If so, do I
do the extend to ALL the paths?
Any insight is appreciated.
If you could, please post a reply directly to me as well as via the
newsgroup
Thanks in advance,
Gregg
