Managing igroups

Tasks to manage igroups

You can use the command-line interface or FilerView to

Create igroups
Destroy igroups
Add initiators (through their WWPNs) to igroups
Remove initiators (through their WWPNs) from igroups
Display all the initiators in an igroup
Set the operating system type (ostype) for an igroup

Creating an igroup

To create an igroup, complete the following step.

Step	Action
1	Enter the following command: *igroup create -f -i [-t ostype] initiator_group* [node_name...]** `-f` indicates that it is an FCP igroup. `-i` indicates that it is an iSCSI initiator. `-t` ostype indicates the operating system of the host. The values are default, solaris, windows, hpux, aix, or linux. Use default if you are using another operating system. initiator_group is the name of the igroup you specify. node_name is an FCP WWPN. Example `igroup create -f -t solaris solaris-group0 10:00:00:00:c9:2b:6b:3c` Result You created an igroup called solaris-group0 that contains the WWPN of the Solaris host associated with that WWPN.

Step

Action

Enter the following command:

igroup create -f -i [-t ostype] initiator_group [node_name...]

-f indicates that it is an FCP igroup.

-i indicates that it is an iSCSI initiator.

-t ostype indicates the operating system of the host. The values are default, solaris, windows, hpux, aix, or linux. Use default if you are using another operating system.

initiator_group is the name of the igroup you specify.

node_name is an FCP WWPN.

Example

igroup create -f -t solaris solaris-group0 10:00:00:00:c9:2b:6b:3c

Result

You created an igroup called solaris-group0 that contains the WWPN of the Solaris host associated with that WWPN.

Destroying an igroup

To destroy one or more existing igroups, complete the following step.

Step	Action
1	If you want to...	Then enter this command...
	Remove LUNs mapped to an igroup before deleting the igroup	lun unmap lun-path igroup Example `lun unmap /vol/vol2/qtree/LUN10 solaris-group5`
	Delete one or more igroups	*igroup destroy `igroup` [igroup,...]* Example `igroup destroy solaris-group5`
	Remove all LUN maps for an igroup and delete the igroup with one command	*igroup destroy -f igroup* [igroup ...]** Example `igroup destroy -f solaris-group5`

Adding an initiator

To add an initiator to an igroup, complete the following step.

Step	Action
1	Enter the following command: igroup add igroup WWPN Caution When adding initiators to an igroup, ensure that each initiator sees, at most, one LUN at a given LUN ID. Example `igroup add solaris-group2 10:00:00:00:c9:2b:02:1f` Result You added the second port of Host2 to the igroup solaris-group2.

Step

Action

Enter the following command:

igroup add igroup WWPN

Caution
When adding initiators to an igroup, ensure that each initiator sees, at most, one LUN at a given LUN ID.

Example

igroup add solaris-group2 10:00:00:00:c9:2b:02:1f

Result

You added the second port of Host2 to the igroup solaris-group2.

Removing an initiator

To remove an initiator from an igroup, complete the following step.

Step	Action
1	Enter the following command: igroup remove igroup WWPN Example `igroup remove solaris-group1 10:00:00:00:c9:2b:7c:0f`

Displaying initiators

To display all the initiators in the specified igroup, complete the following step.

Step	Action
1	Enter the following command: *igroup show [igroup]* Example `igroup show solaris-group3`

Setting the ostype

To set the operating system type (ostype) for an igroup, complete the following step.

Step	Action
1	Enter the following command. igroup set igroup ostype Example `igroup set solaris-group3 solaris`
