Figure 65 Example of setting up Speed LSAN tag
Rules for LSAN tagging
Note the following rules for configuring LSAN tags:
• Configure the tags on the FC router, and not on the edge switches. If Virtual Fabrics are enabled,
configure the tags on the base switch on which the EX_ and VEX_Ports are located. You then have to
ensure that the LSAN zones in the edge fabrics incorporate the tags correctly.
• The LSAN tags are configured per FC router, not per fabric. If the backbone fabric has multiple FC
routers, HP recommends that you configure the LSAN tags on all of the FC routers.
• The FC router must be disabled before you configure the Enforce tag. Configuring the Speed tag does
not require that the FC router be disabled; however, after configuring the Speed tag, you must toggle
the host or target port to trigger the fast import process.
• The tag is from 1 to 8 alphanumeric characters.
• You can configure only one Speed tag on an FC router, and up to 8 Enforce tags on an FC router. The
maximum number of tags (Enforce and Speed) on an FC router is 8.
• Up to 500 Speed LSANs are supported.
Configuring an Enforce LSAN tag
1. Log in to the FC router as admin.
2. Enter the following command to disable the FC router:
switchdisable
3. Enter the following command to create an Enforce LSAN tag:
fcrlsan --add -enf tagname
where tagname is the name of the LSAN tag you want to create.
4. Enter the following command to enable the FC router:
switchenable
5. Change the names of the LSAN zones in the edge fabrics to incorporate the tag in the names.
