Port A/B World Wide Name (WWN) Submenu
Manufacturing generates normal drive node and port A/B
Note:
WWNs as a set, and stores them in the drive EEPROM. The format
is:
Drive Node: H=500104F0 (StorageTek brand device), L=yyyyyyyy.
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).
You can create or edit a Custom WWN as required for special circumstances. When
Custom WWNs are used, Port A, Port B, and Drive Node WWNs should all be
changed to 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.
Defaults to the last saved selection.
H=500104F0 comprises the first half of a unique 64-bit WWN that identifies the specific
port node. This first half includes a company identification (characters 2 through 6);
and for StorageTek branded devices, the company ID is 00104F.
You would not typically edit the first half of a WWN.
Note:
L=yyyyyyyy comprises the second half of the 64-bit WWN that identifies this specific
port node. Typically, only the last character is different than the other port node.
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.
