From PP/Basic to Linux Native Multipath
I am supposed to change Redhat 5.x on a Clariion CX4-120 from powerpath/Basicfailover to Linux Native-multipath.
What are the pros and cons when PP/Basic is compared with Native Multipathing ?
What should be the best procudure to follow for this procedure ? Should it be ?
a) umount the relevant filesystems
b) edit /etc/fstab to exclude the LUNs
c) remove powerpath completely and reboot host
d) add/enable NMP service
e) scan for LUNs
f) test by mounting/accessing
g) edit /etc/fstab and reboot
Any details on steps d,e,f that could help me ?
