migrate

hi,

i migrate an old SAN to a new SAN using vxvm on centos.

i see the new disk from new SAN -/dev/sdb and i add this disk under DG where is the old disk then i make mirror between them.Then i remove the old disk from DG.Then i connect the cable from old SAN to new SAN-i see then /dev/sdd as second path to the new disk.If i use now multipath to create /dev/mapper/mpath with underlying disks /dev/sdb /dev/sdd then is there necessary to perform things under vxvm in order that vxprint to see /dev/maper/mpath instead /dev/.sdb?

tnx

if you follow one of the above two technotes, both your new luns and VxVM should work just fine

No you dont need to anything else. DMP will work with what OS gives it.
