Drive Node WWN Submenu
Note : You can create/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 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 dynamic WWN (dWWN) feature, automatically sets the drive Custom WWN setting to a
library-determined WWN.
H=500104F0
Defaults to last saved selection.
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. 1. Do one of the following:
■
Press Menu to bypass
■
Press Select to start the
change mode:
2. Press Select to increment character until
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
Defaults to last saved selection.
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. 1. Do one of the following:
■
Press Menu to bypass
■
Press Select to start the
change mode:
2. Press Select to increment character until
desired value appears, then press Menu .
3. Repeat step 2 for each character.
4. Press
Menu
to advance to the next
submenu; or, press Select to restart the
change mode.
Note : Manufacturing generates “Normal” drive node and port A/B WWNs as a set, and stores them in the drive
EEPROM. The 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)
Drive Node Custom/Normal WWN Submenu
Note : This submenu only appears if a Custom WWN is in use, or is being created/edited.
WWN Custom Appears when a Custom WWN is in use, or
is being created/edited.
WWN Custom also appears when the drive
is using dynamic WWN, set by a library
invoking dWWN.
Do one of the following:
■
Press Menu to bypass to the next
submenu.
■
Press Select to toggle the selection to
WWN Normal
WWN Normal
Selection recalls the stored Normal WWN
from the drive EEPROM. Do one of the following:
■
Press Menu to recall the stored Normal
WWN, and advance to the next
submenu.
