SAN management with Admin Domains
15
Admin Domains and LSAN zones
LSANs under each Admin Domain are collated into a single name space and sent out to FCR
phantom domains using the following format:
<original_LSAN_name>_AD<AD_num>
For example, a zone with name lsan_for_linux_farm in AD5 is internally converted to
lsan_for_linux_farm_AD005.
LSAN zone names in AD0 are never converted for backward compatibility reasons.
The auto-converted LSAN zone names might collide with LSAN zone names in AD0 (for example, in
the above example, if AD0 contains lsan_for_linux_farm_AD005, this causes a name collision).
Fabric OS does not detect or report such name clashes.
LSAN zone names greater than 57 characters are not converted or sent to the FCR phantom
domain. See Chapter 21, “Using the FC-FC Routing Service,” for information about LSAN zones.
Configuration upload and download in an AD context
The behavior of the configUpload and configDownload commands varies depending on the AD
context and whether the switch is a member of the current Admin Domain. In the AD context, these
commands include only the zone configuration of the current Admin Domain. If the switch is a
member of the Admin Domain, all switch configuration parameters are saved and the zone
database for that Admin Domain is also saved.
Table 76 lists the sections in the configuration file and the Admin Domain contexts in which you can
upload and download these sections. See Chapter 8, “Maintaining the Switch Configuration File,”
for additional information about uploading and downloading configurations.
NOTE
You cannot use configDownload to restore a single Admin Domain. To restore a single Admin
Domain, you must first delete all Admin Domains and then issue configDownload to restore them.
The configDefault command does not clear zone or Admin Domain database information. This
command is allowed only if the switch is a member of the current Admin Domain.
