HP Matrix Operating Environment and HP Storage Provisioning Manager support for port groups

3. Save the SPE. (This will cause SPM to un-present the volume(s) from the host(s).)
4. When the operation is completed, modify the SPE again.
5. Check the
Mask
checkbox for the previously unmasked volume(s*).
6. Save the SPE. (This will cause SPM to re-present the volume(s) to the host(s).)
When all activations within SPM are complete, the Rezone script can be rerun on the initiator WWN and all of its services.
* Many volumes/services can be operated on at the same time using these steps, saving time. Simply uncheck the
Mask
checkbox for all affected volumes before saving the SPE. SPM will perform an unpresent operation for each volume.
Example of running Rezone.ps1
Figure 4
shows an example of using the Rezone PowerShell script. The definition for the port group being zoned,
“SANB_Group2”, can be found in the port group definition examples earlier in this document.

Output from a typical running of the Rezone.ps1 script.
Final actions
When all rezoning operations for the impacted servers are complete, the last action is to return the servers back to their
original state. If the volumes were redundant, and the rezoning done to the live servers, then there is no additional action.
Otherwise, servers will need to be restarted. If they are VM hosts, then all VM guests originally moved off of these servers
should be moved back.
Additional Information Using Port Groups in SPM
This section discusses additional topics specific to using port groups and the controller port white list from within SPM.
Note:
These capabilities are not available through Matrix, but can impact storage provisioned through Matrix.
Controlling port group behavior within SPM
Port group behavior can be controlled within SPM using the port group configuration file and by using Fibre Channel port
group requirements within SPM services. If port groups are configured for an array, when creating an SPM service using a
volume on that array, SPM will zone each initiator to the ports in one port group. If a service request includes a port group
requirement within its initiator endpoint requirement and there is a port group defined with the same name for the array,
SPM will use the ports in the group with the name specified by the requirement. If a service request does not include a port
group requirement within an initiator endpoint requirement or if there is such a requirement but the specified port group
name does not match the name of any port group on the array, SPM will use the port group containing a target port that is
used by the least number of SPM storage services. If a number of ports are used by the least number of SPM storage
services, SPM will choose one at random. Ports that are not mentioned in the port group file are treated as if they are in a
port group containing only that port. Arrays not mentioned in the port group file are treated as if all ports on the array are in
a single group. These default groups are not named, and cannot be specified in a port group requirement. Please see the HP
Storage Provisioning Manager (SPM) User Guide for more information.
