I recently set up a freebsd ZFS SAN. Using istgt i have set up my iscsi target.
istgt version 0.5 (20121028)
normal mode
using kqueue
using host atomic
LU1 HDD UNIT
LU1: LUN0 file=/dev/zvol/zroot/iscsi, size=17592186044416
LU1: LUN0 34359738368 blocks, 512 bytes/block
LU1: LUN0 16384.0GB storage for iqn.2015-06.local.mydomain.san:iscsi
LU1: LUN0 serial 10000001
LU1: LUN0 read cache enabled, write cache enabled
LU1: LUN0 command queuing enabled, depth 32
I have 2 esx host boxes that I would like to access the same LUN. Is this best practice or do I need to an additional LUN to the san for the second host to access? Or will this work if both host boxes are clustered?
As it stands right now host box 1 sees the LUN just fine. Host box 2 does not.
