I am using RHEL 5 .3 installed on HP hardware . its on cluster veritas on which one node works fine and second node disk is on predective disk faliure.
now i want to replace it with second hardisk using lv mirroring.
My OS installed on LV's. means all partition including root is on LV . apart from boot partition.
i am planning to add one new harddisk in a slot so that i can create lv mirroring of predective faliure disk than transfer the os to the new one after creation.
So pls guide with the right steps so that no problem occurs and with very less downtime.
Pls also guide any risk involvement in this ? is this the right way for doing it..?
