Galaxy Metal Gear 65 manual Configuring InfoShield

RAID Management

3.4.4.3Configuring InfoShield

Once you set up host nicknames, you can easily set up your InfoShield. This is where you determine which hosts can access each partition LUN.

You set up InfoShield by either excluding or including hosts on a list for each partition LUN. The list can include or exclude up to 64 specific hosts or all hosts for each partition LUN.

The InfoShield information is stored as part of the array’s metadata using the WWN for each host. If you install a new SM, the array partition’s InfoShield will remain. The InfoShield will also remain if you change the partition’s LUN.

Note Changes to InfoShield take effect immediately, therefore, you should make changes that limit access to partitions when the partitions are not in use.

To set up InfoShield:

1From SAM, select Manage Galaxy 65 Subsystem > LUN Management > Partition Menu > InfoShield. The InfoShield page displays.

2In the Select an Array to View/Change InfoShield Information panel, select the array whose partition you want to control access to.

3In the Select a Partition to View/Change InfoShield Information panel, select the partition name.

4In the InfoShield Type for Array panel, select the InfoShield type you want to use and click Change InfoShield Type.

The panel shows the current InfoShield type in the drop-down list. The default setting for each partition LUN is Include All Hosts. This results in all hosts being able to access all partitions. Changing the InfoShield type does not add or remove any hosts in previously created lists.

•Include All Hosts: Permits all hosts on the network to access the selected partition. This is the default InfoShield type. This results in all hosts being able to access the partition. If you have already created an include or exclude list, you can use this option to override the list. Your existing list is retained and you can display, add, or remove hosts from the list.

•Include Listed Hosts: Lets you enter or select the WWNs of the specific hosts you want to be able to access the selected partition. The list of WWNs and nicknames that displays contains the last 64 hosts that started or that you gave a nickname. If you know other WWNs or nicknames, you can enter the WWN or nickname.

•Exclude All Hosts: Permits no hosts on the network to access the selected partition. If you have already created an include or exclude list, you can use this option to override the list. Your existing list is retained and you can display, add, or remove hosts from the list.

•Exclude Listed Hosts: Lets you enter or select the WWNs or nicknames of the specific hosts you do not want to be able to access the selected partition. The list of WWNs and nicknames that displays contains the last 64 hosts that started or that you gave a nickname. If you know other WWNs or nicknames, you can enter the WWN or nickname.

Whether you use an include or exclude list depends on your needs. You may want to determine which list would be shorter and create the shorter list.
