I created a LUN and attached it to a linux host. Then I ran the hot_add utility to update the partition table.
The multipath entry looks like this:
Code:
600a0b800049cc2800000c0551465bca dm-0 IBM,1726-4xx FAStT
[size=600G][features=0][hwhandler=0]
\_ round-robin 0 [prio=1][active]
\_ 2:0:1:4 sdm 8:192 [active][ready]
\_ round-robin 0 [prio=1][enabled]
\_ 1:0:1:4 sdl 8:176 [active][ready]
\_ round-robin 0 [prio=0][enabled]
\_ 2:0:0:4 sdg 8:96 [failed][faulty]
\_ round-robin 0 [prio=0][enabled]
\_ 1:0:0:4 sdd 8:48 [failed][faulty]
So I created a partition with /dev/sdm1, but after that when I am going to create the filesystem, its giving the error:
Code:
mkfs.ext3 /dev/sdm1
/dev/sdm is apparently in use by the system; will not make a filesystem here!
While its not being used any pid, its giving the error and not allowing to create filesystem.
With the same way I created and attached many LUNs before but not working now.
can anyone advice, what may be the issue ??
