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
