I had a system that I was testing zfs on using EMC Luns to create a striped
zpool without using the multi-pathing software PowerPath. Of coarse a storage
emergency came up so I lent this storage out for temp storage and we're still
using. I'd like to add PowerPath to take advanage of the multi-pathing in case
I lose and SFP (or entire switch for that matter) but I'm not exactly sure what
I can do.
So my zpool currently looks like:
######################################################
# zpool status -v
pool: myzfs
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
myzfs ONLINE 0 0 0
1234567890 ONLINE 0 0 0
1234567891 ONLINE 0 0 0
#######################################################
So how would I change the path after I install PowerPath to use the multi-path?
So 1234567890 would be equal to /dev/dsk/emcpower1 and 1234567891 would be
equal to /dev/dsk/emcpower2.
In the end it would look like:
######################################################
# zpool status -v
pool: myzfs
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
myzfs ONLINE 0 0 0
emcpower1 ONLINE 0 0 0
emcpower1 ONLINE 0 0 0
#######################################################
I would image (because I haven't tried it yet) that it would require using zfs
export/import in order to make this happen. Has anyone tried this? Am I
fubar? Thanks for the help! Great forum btw...
