Editing resource groups

Note the following restrictions for editing resource groups:

• Only resources allocated to meta_resource can be added to resource groups.

• Resources removed from a resource group are returned to meta_resource.

• No resource can be added to or removed from meta_resource.

• The name of the meta_resource group cannot be changed or used for any resource group other than the meta_resource group.

• Duplicate occurrences of the same name are not allowed.

• Resource group names can include alphanumeric characters, spaces, and the following symbols: ! # $ % & ' ( ) + - . = @ [ ] ^ _ ` { } ~

• Resource group names are case-sensitive.

• LDEVs with the same pool ID or journal ID cannot be added to multiple resource groups or partially removed from a resource group. For example, if two LDEVs belong to the same pool, you must allocate both to the same resource group. You cannot allocate them separately.

You cannot partially remove LDEVs with the same pool ID or journal ID from a resource group. If two LDEVs belong to the same pool, you cannot remove LDEV1 leave only LDEV2 in the resource group.

Use the sort function to sort the LDEVs by pool ID or journal ID. Then select the IDs and add or remove them all at once.

• Host groups that belong to the initiator port cannot be added to a resource group.

• To add or delete DP pool volumes, you must first add or delete DP pools.
