Drive Node WWN Submenu
Note: You can create or edit a Custom WWN as required for
special circumstances. When Custom WWNs are used, Drive Node,
Port A, and Port B WWNs should all be changed to the designated
Custom WWNs to meet special circumstances.
Make sure the Custom WWN is registered in the Host interface
software. Unregistered or duplicate WWNs cause Host interface
anomalies. Libraries using the dynamic WWN (dWWN) feature
automatically set the drive Custom WWN setting to a
library-determined WWN.
H=500104F0
comprises the first half of a unique 64-bit node WWN that identifies this
drive node. This first half includes a company identification (characters 2 through 6);
and for StorageTek branded devices, the company ID is 00104F. Therefore, you would
not typically custom edit the first half of a WWN.
Note: Manufacturing generates the normal drive node and port
A/B WWNs as a set and stores them in the drive EEPROM. The
WWN format is:
Drive Node: H=500104F0 (StorageTek brand device), L=yyyyyyyy. (lowest
of set).
Port A:
H=500104F0, L=yyyyyyyy (last character, one higher than drive
node).
Port B:
H=500104F0, L=yyyyyyyy (last character, one higher than port A
node).
Defaults to the last saved selection.
Procedure:
1. Do one of the following actions:
a. Press Menu to bypass.
b. Press Select to start the change mode.
2. Press Select to increment the character until the desired value appears, then press
Menu.
3. Repeat step 2 for each character.
4. Press Menu to advance to the second half of the WWN; or, press Select to restart
the change mode.
L=yyyyyyyy
Comprises the second half of the 64-bit WWN that identifies this specific node.
Typically, only the last character is different than the port nodes. Generally, when
setting a Custom WWN in a drive, you edit the second half of the WWN to replicate
the second half of the WWN which was in use for the removed drive.
Defaults to the last saved selection.
Procedure:
1. Do one of the following actions:
a. Press Menu to bypass.
