we are currently using 1 CX4 and 1 VNX attached via SAN to our linux (SLES11SP1) cluster
using the system multipath driver.
Has anybody tried to attach lun's from a different storage provider to the same HBA ?
Does it work or MUST we use dual port HBA ?
For 23 servers this is really expensive (exchange all hba's, san ports ...)
well we use dedicated zoneing for each path
Box1_HBA1-VNX1_SPA # 1 zone
Box1_HBA1-VNX1_SPB # 2 zone
Box1_HBA1-CX4_1_SPA # 3 zone
Box1_HBA1-CX4_1_SPB # 4 zone
Box1_HBA1-other_SPA # 1 zone
Box1_HBA1-other_SPB # 2 zone
But did not see any device attached to Box1_HBA1 see or at least can comunicate to all other devices ?
This was the main reason to ask ! Or does each zone leeds to a sperate comunication channel , so
SPA can not see or talk to SPB ?
I'm not an expert at SAN things, therefore I'm asking all the things ....
