Defining LU paths
The Storage Administrator (Provisioning) role is required to perform this task.
In a fibre channel environment, you must define LU paths and associate host groups with logical volumes. For example, if you associate a host group consisting of three hosts with logical volumes, LU paths are defined between the three hosts and the logical volumes.
To define LU paths:
Perform one of following to display the Add LUN Paths window.
For Hitachi Command Suite:
On the Resource tab, expand the Storage Systems tree. On the target storage system, click Port / Host Group. On the Host Groups / iSCSI Targets tab, click Add LUN Paths.
For Storage Navigator:
On the General Tasks in Hitachi Device Manager - Storage Navigator, select Add LUN Paths.
Expand the Storage Systems tree and select Ports / Hosts Groups / iSCSI Targets. On the Host Groups / iSCSI Target tab, click Add LUN Paths.
Expand the Storage Systems tree and select Ports / Hosts Groups / iSCSI Targets, select the relevant port. In the Host Groups tab, click Add LUN Paths.
Expand the Storage Systems tree and select Ports/Hosts Groups/iSCSI Targets. Click Actions > Logical Device > Add LUN Paths to open the window.
Select the desired LDEVs from the Available LDEVs table, then click Add.
Selected LDEVs are listed in the Selected LDEVs table.
Click Next.
Select the desired host groups from the Available Host Groups table, then click Add.
Selected host groups are listed in the Selected Host Groups table.
Click Next.
Confirm the defined LU paths.
To change the LU path settings, click Change LUN IDs and type the LUN ID that you want to change.
To change the LDEV name, click Change LDEV Settings. In the Change LDEV Settings window, change the LDEV name.
Click Finish.
In the Confirm window, confirm the settings, in Task Name type a unique name for this task or accept the default, then click Apply.
If Go to tasks window for status is checked, the Tasks window opens.
