I am using multipathing on rhel4 u3 x86_64 with EVA4000 and HSV200 controller. I had a few questions: 1. lsmod shows the below modules dm_mirror 29017 0 dm_round_robin 4929 1 dm_multipath 21841 2 dm_round_robin dm_mod 67457 9 dm_mirror,dm_multipath Do need to insert "multipath" module also ? If yes then what it is for ? without using multipath module I can see multiple paths in multipath -v2 -l output 2. How do I ensure that the same device gets mounted across reboots ? I verified that across the reboots mpath6 refers to the same device, wwid is same for mpath6 across reboots # multipath -v2 -l mpath6 (3600805f300176640a435a927359c0003) [size=440 GB][features="0"][hwhandler="0"] \_ round-robin 0 [active] \_ 2:0:0:1 sdag 66:0 [active][ready] \_ 0:0:0:1 sda 8:0 [active][ready] I have /dev/mapper/mpath6 in /etc/fstab and it works correctly. # ls -l /dev/mpath/mpath6 lrwxrwxrwx 1 root root 7 Jul 18 06:13 /dev/mpath/mpath6 -> ../dm-6 What is the difference if I use /dev/dm-6 ? which will be better ? Thanks. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
