9. Click Finish.
The new LUN path is added to the Encryption Disk LUN View table.
10. Click OK on the LUN view to commit the operation.
NOTE
With the introduction of Fabric OS v7.1.0, the maximum number of uncommitted configuration
changes per disk LUN (or maximum paths to a LUN) is 512 transactions. The 512 LUN
operations can be for the same LUN or be subjected to 25 distinct LUNs. This change of
restriction in commit limit is applicable when using the Management application only. Earlier
Fabric OS versions allowed a maximum of 25 uncommitted changes per disk LUN. Adding or
modifying more than 25 paths on the same LUN is not recommended unless the LUN is
encrypted.
In environments where there are multiple paths to the same LUNs, it is critical that the same
LUN policies are configured on all instances of the LUN. Be sure to return to the Encryption
Disk LUN View dialog box to determine if there are configuration mismatches. Check under
Encryption Mode for any entries showing Mismatch. To correct the mismatch, click the
incorrect mode to display the options, then select the correct mode. (Refer to
Figure 382 .)

When you correct a policy on a LUN, it is automatically selected for all paths to the selected
LUN. When you modify LUN policies, a Modify icon displays to identify the modified LUN entry.
