Adding target disk LUNs for encryption
20
•
LUN table: Available LUNs identified by the following:
•
Host
•
LUN Number
•
LUN Serial Number
•
Current LUN State: Options are Encrypted, which is automatically selected if the LUN
has a key ID; Clear Text, and <select> for LUNs without a key ID. User selection is
required.
•
Key ID: Identifies the key ID for discovered LUNs.
•
Thin Provision LUN: Identifies if the new LUN is a thin provisioned LUN.Options are Yes, No,
Unknown, or Not Applicable.
NOTE
Thin provision support is limited to Brocade-tested storage arrays. The thin provision LUN
status will be displayed as Yes for supported storage arrays only.
•
New LUN: Displayed only if remote replication is enabled.
6. Select the LUN from LUN list.
7. Set the Current LUN State as required. If the LUN already has an existing key ID, the Current
LUN State field is automatically set to Encrypted. You can accept the automatically assigned
state or change this value if desired.
8. If REPL Support was enabled by the Configure Switch Encryption wizard, a New LUN check box
is presented and enabled by default. If this LUN is to be paired with another LUN for SRDF data
replication, the New LUN option must be enabled. Refer to
“Metadata requirements and
remote replication” for information about how this option works. If REPL support was not
enabled, this check box is not displayed.
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 (
Figure 299 ).
