Will the device names change on my server, if it is moved over to different SAN fibre switch?

I think it would.

Hope this helps.

It absolutely will change the device names. It is however possible to renumber the device names after the switch.

Document KBRC00004879 tells how to do that.

As a precaution, I'd back up the data and do a vgexport on the volume group. You can then vgimport after the switch, rebuild the volume group and minimize the disruption.

Can anyone suggest me what are the steps involved so that i can retain the same device names, VG and LV's by moving the server to different SAN switch. I'll greatly appreciate any suggestions and procedures.
Thank you

We completed the task successfully, The device names will change when you move over to different SAN switch. Do a VGSCAN and VGCHANGE for all the Volume groups and mount them.
