Thanks, Simon, <span style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt;">This is what I thought was the case, and in fact I couldn't see it was not. In reality there -are- JBODs involved, so that was a somewhat
hypothetical use case initially.</span></div>

When you create the file-system, you create NSD devices (on physical disks ? usually LUNs), and then assign these devices as disks to a file-system. This sounds straight forwards.<br>
<br>
Note GPFS isn?t really intedned for JBODs unless you have GNR code.<br>

Subject: [gpfsug-discuss] Identifiable groups of disks?<br>
<br>
Scenario:<br>
<br>
<br>
* one set of JBODS<br>
* want to create two GPFS file systems<br>
* want to ensure that file system A uses physical disks a0, a1... an-1 and file system B uses physical disks b0, b1... bn-1<br>
* want to be able to assign specific sets of disks a0..an-1, b0..bn-1 on creation<br>
* Potentially allows all disks b0..bn-1 to be destroyed if required whilst not affecting a0..an-1<br>
Is this possible in GPFS?<br>
<br>
Regards<br>
