Hi,

I have Custer Service running on Windows 2000 (MSCS) with one queue manager and I only have 2 drives on the external shared array (Q:\ for the quorum and D:\ for the actual shared data). Now, can I create one more queue manager which will store its data on the shared driver D:\ ?

Thanks,

Sas

Well, I've tried it and it worked, if any cares! Futhermore, I found the following info. in the WebSphere 5.3 System Administration Guide:

"...you can choose one of the following setups:

- One shared disk for all queue managers to use. In this configuration, if a
problem occurs with any queue manager, all the queue managers failover to the other computer as a group.

- Each queue manager with its own shared disk. In this configuration, if a
problem occurs with one queue manager, it alone fails over to the other
computer without affecting the other queue managers.

- A mixture of the first two setups.

..."

(Sorry - was away!)

Just to add to what you have said, you need to ensure each qmgr who is on the same shared disk has a dependency on that disk. Aside from this, the only impact of doing it is that a single failure will move all the qmgrs rather than an individual one.
