How to Create a Disk Set
Before You Begin
The disk set that you intend to create must meet one of the following requirements:
-
If the disk set is configured with exactly two disk strings, the disk set must connect to exactly two nodes and use two or three mediator hosts. These mediator hosts must include the two hosts attached to the enclosures containing the disk set. See Configuring Dual-String Mediators for details on how to configure dual-string mediators.
-
If the disk set is configured with more than two disk strings, ensure that for any two disk strings S1 and S2, the sum of the number of drives on those strings exceeds the number of drives on the third string S3. Stated as a formula, the requirement is that count(S1) + count(S2) > count(S3).
Example 4-2 Creating a Disk Set
The following command creates two disk sets, dg-schost-1
and dg-schost-2
, with the nodes phys-schost-1
and phys-schost-2
specified as the potential primaries.
phys-schost# metaset -s dg-schost-1 -a -h phys-schost-1 phys-schost-2 phys-schost# metaset -s dg-schost-2 -a -h phys-schost-1 phys-schost-2
Next Steps
Add drives to the disk set. Go to Adding Drives to a Disk Set.
