Managing initiator groups

You can use the command-line interface or FilerView to

Create initiator groups
Destroy initiator groups
Add initiators (through their WWPNs) from initiator groups
Remove initiators (through their WWPNs) from initiator groups
Display all the initiators in an initiator group
Set the operating system type (ostype) for an initiator group
Note
When using the command line, you can get command-line syntax help from the command line.

To create an initiator group, complete the following step.

Step	Action
1	Enter the following command: *igroup create -f -i [-t ostype] igroup* [unique identifier...]** -f indicates that it is an FCP initiator group. -i indicates that it is an iSCSI initiator. ostype indicates the operating system of the host (Windows or Solaris). igroup is the name of the initiator group you specify. unique identifier is either an iSCSI node name or an FCP WWPN. Example `igroup create -f -t solaris solaris-group0 10:00:00:00:c9:2b:6b:3c` Result You created an initiator group 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] igroup [unique identifier...]

-f indicates that it is an FCP initiator group.

-i indicates that it is an iSCSI initiator.

ostype indicates the operating system of the host (Windows or Solaris).

igroup is the name of the initiator group you specify.

unique identifier is either an iSCSI node name or an FCP WWPN.

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

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

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

Note
An initiator group cannot be destroyed if any LUNs are mapped to it, unless you use the -f parameter.

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

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

Step	Action
1	Enter the following command: igroup add igroup WWPN Caution When adding initiators to an initiator group, 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 initiator group solaris-group2.`

Step

Action

Enter the following command:

igroup add igroup WWPN

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

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

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

To remove an initiator from an initiator group, 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`

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

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

To set the operating system type (ostype) for an initiator group to Solaris or Windows, complete the following step.

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

To get command-line syntax help, complete the following step.

Step	Action
1	Enter the following command: igroup help subcommand
