Licenses
Some features require licenses in order to work properly. To view a list of features and their
associated licenses, refer to the Fabric OS Administrator’s Guide. Licenses are created using a
switch’s License Identifier
so you cannot apply one license to different switches. Before calling your
switch support provider, verify that you have the correct licenses installed by using the licenseShow
command.
Symptom A feature is not working.
Probable cause and recommended action
Refer to the Fabric OS Administrator’s Guide to determine if the appropriate licenses are installed
on the local switch and any connecting switches.
Determining installed licenses
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the licenseShow command.
A list of the currently installed licenses on the switch is displayed.
Time
Symptom Time is not in-sync.
Probable cause and recommended action
NTP is not set up on the switches in your fabric. Set up NTP on your switches in all fabrics in your
SAN and metaSAN.
For more information on setting up NTP, refer to the Fabric OS Administrator’s Guide.
