74 Sun StorEdge 3900 and 6900 Series 2.0 Troubleshooting Guide • March 2003
Sun Proprietary/Confidential: Internal Use Only
The Sun StorEdge network FC switches in a Sun StorEdge 3900 or 6900 configuration
now support the Sun StorEdge SAN 4.1 Release. You can upgrade the switches to
support the 402xx 2 Gbit-compatible firmware.
Caution – Use caution when upgrading back-end switches to the 2 Gbit-compatible
firmware. Use only the setswitchflash command, which performs the upgrade
and creates the zone configuration in a controlled manner (refer to the Sun StorEdge
3900 and 6900 Series 2.0 Reference and Service Guide for the procedures).
Zone Modifications
You should not modify the shared zone set on the back-end switches—doing so can
cause an error (Error State 50) on the virtualization engine. If you determine,
however, that you must modify the shared zone set, follow these steps:
1. Offline the T ports (interswitch links).
2. Offline the virtualization engine ports.
3. Modify the zone on one switch while the other switch continues to run.
4. Online the T ports (interswitch links).
5. Allow the zone database to merge.
6. Online the virtualization engine ports.
You can use the sanbox2(1M) command to offline the ports. For example:
By default:
■ T ports are 671415
■ Virtualization engine ports are 08
# /opt/SUNWsecfg/flib/sanbox2 -x switch-ip-addr port -state
