A key requirement of today’s complex data center environments is to be able to deliver mission-critical data quickly, at any time, without interruptions or delays.

You have finished all the steps needed to set up Linux to boot from a multipath SAN. For example, use the modprobe -r command to remove a driver and the modprobe command to install a driver. For my virtual network, Ubm bound it to the eth0 adapter specifically. NPIV is not supported in this configuration. qloigc
