Hi all,
there are two servers in our ncs cluster and they are mounting separate partitions from the msa 1000 san. The msa 1000 has three partitions.

-sbd for ncs
-an nss partition with two volumes mounted by server 1
-an ext3 partition mounted by server 2

one hdd in the 10-disk array had failed. my question is - is it okay to remove the failed disk from the array and replace it with a new one? infact I need to remove it to check the hp serial number!

or should I bring the cluster offline and then unmount the volumes before doing it.

thanks in advance,
