Figure 74: LUN Masking tab
LUN Masking Conventions and Guidelines
LUN icons in the discovery-tree reflect the live mask state currently in use by the driver. Green LUN
icons indicate unmasked LUNs. Gray LUN icons indicate masked LUNs. Red text indicates that a LUN
mask has been changed, but not applied (saved).
LUN Masking Column Definitions
• LUN – The FC LUN number.
• On Reboot – The 'On Reboot' column shows the mask configuration currently saved to the
configuration file on disk (Solaris SFS) or to the Registry (Windows). Normally, for a specific
LUN, the states reported in the 'On Reboot' and 'Current' column are identical. However, there
can be times where these do not match. For example, the hbacmd utility can be used to change
only the 'Current' mask state for a LUN and not touch the 'On Reboot' mask state contained in
the configuration file.
• Current – The 'Current' column displays the live mask state currently in use by the driver. When
you first see the LUN Masking tab, the mask states displayed in the 'Current' column are
identical to the mask states for the corresponding LUNs in the discovery-tree.
To change the mask status of a LUN:
1. Select Host view.
2. From the discovery-tree, select the SCSI target whose LUN masking state you want to change.
A set of LUNs appears below the selected SCSI target.
