Quarantining resources
Quarantine is a state flag on each resource that when set is referred to as quarantining the resource.
When a resource is quarantined, SPM does not use the resource to construct new services nor
does SPM perform any automated configuration on the resource. SPM leaves it in its current state.
Existing resourced services using quarantined resources therefore cannot be reconfigured
(reactivated), but otherwise are unaffected by the quarantine state.
The quarantine state may be set or unset manually by the administrator and may also be set by
SPM. SPM never clears the quarantine state; the administrator must clear the state when it is safe
for SPM to begin using the resource again.
A Change Quarantine option is available on the actions menu for arrays, volumes, storage pools,
and networks.
Resources are placed in quarantine by:
• The recovery process—As part of SPM recovery, after an SPM catalog is restored from backup
and SPM is started in Internal Recovery mode, all resources are resynchronized from the
device. If SPM detects a configuration change between the recovered catalog and the device
then the resource is put into quarantine. This usually means something happened to the resource
or catalog after the SPM catalog backup occurred that was lost on restore, and the administrator
may need to update the SPM catalog manually before the resource is safe to be brought out
of quarantine. For more information on performing this process, see the Backing up and
restoring HP Insight Management 7.2 Central Management Server (Windows) white paper
at http://www.hp.com/go/matrixoe/docs.
• Service deactivation—If a Service Deactivation Policy of “Quarantine Resource” is used, SPM
removes the volume's presentations and places the volume in quarantine when the service is
deactivated. This is useful if the administrator does not want volume data to be lost or
overwritten at or after service deactivation until archive or aging processes outside of SPM
have been done.
• Manually set by the administrator—At any time the administrator can set or unset the quarantine
state of a resource. This may be useful when performing maintenance or upgrades on a
resource to ensure SPM does not attempt to perform automation on the resource during the
maintenance window, or at any other time the administrator wants to prevent SPM from
performing configuration of a resource.
Managing templates
Storage architects are able to perform the following operations on templates:
• Create a new template.
• Modify an existing template. (You are prompted whether to change existing services based
on the template.)
• Modify template requirements on an existing storage service.
• Delete a template if there are no existing storage services based on it.
Storage architects and admins can perform the following operations on templates:
• Add or remove templates to and from a security group.
• View template details, contents, or both.
• View all services based on a template.
• View template of a service.
