Figure 8-14 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) 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.
