Hi,

I have a RHEL server that have dm-multipath enabled, the proble we have now is the psuedo device name keep changing after the server is rebooted, is there a way to make the psuedo name consistence across reboot?

for example dm-95 is dm-56 before reboot.

mpath56 (360060e800549690000004969000009c0) dm-95

Thanks,

Robert.

should'nt you be accessing them as /dev/<volume grou name>/<logical volume name> ?
