Raidlevel multipath on SAN

[Shen-Yi]

I am running a Raid level Multipath on ES3.0 connected thru a Emulex LP8000 to FC Switch and to VA7100. everytime I configure a raid multipath, I am unable to raidstop it.... it complains device busy. anybody encountered such an issue?
Reason being that I am configuring a Cluster and if raidstop fails, Package will not failover.

First, you may want to use mdadm - it is easier to use for administering raid.

Do you have anything mounted? You need to unmount it first.

If you fail the devices, then you should also be able to stop it.

Thanks for your reply. I tried 2 methods of using mdadm and creating a raidtab. Without even a file system created on the md(s), it still refuses to stop.

Do you know of any way to --really-force a raidstop. I have seen much documentation on creating raid, but not too much on troubleshooting such issues.
