136 Advanced Setup Instructions
This command will change the WWN for Fibre Channel Ports.
This should only be done when replacing a failed SNC. You should never
operate 2 FC devices that are set to the same WWN. This may destabilize
your SAN.
The unit will be rebooted after the WWN change.
Do you want to proceed (enter "yes" to continue) :
Step 3 Type the word
yes
and press Enter .
The following message is printed:
Enter the new WWN (or q to quit):
Step 4 Enter all eight bytes of the new WWN. Each byte of the entry should be delimited by colons. For
example, enter:
00:00:00:30:8C:02:70:21
Step 5 The first five bytes of the entry are checked. If the entry is valid, you are prompted for a
password. Type the password
OverrideWWN
and press Enter .
This causes the SNC to reboot.
Step 6 When the SNC has rebooted, issue the
fcShowNames
command to verify the change.
Verify that the output in the Node Name column is correct.
If only a single FC port is to be changed, use the
wwnPortSet
command to set the WWPN and WWNN for
a single FC port.
Also, AMC can be used to verify that the WWNs are detected correctly following the change. For the failover
or self-domain solution, AMC will issue a warning message indicating duplicate WWNs have been detected.
This means the setup is performed correct.
CAUTION
The
wwnGlobalSet
command requires that the first byte be entered as "00"
even if
fcShowNames
displays "10" in that position.
CAUTION
When entering the WWN, the firmware will confirm that the node ID and OUI
match the existing values. This prevents a user from accidentally making the
SNC appear as another vendor’s device.
Note
If one of the WWN fails to change, run the
wwnPortSet
command again.
