6.11.1 Using the emxmgr Utility to Display Fibre Channel Adapter
Information
The primary use of the emxmgr utility for TruCluster Server is to display
Fibre Channel information.
Use the emxmgr -d command to display the presence of KGPSA Fibre
Channel adapters on the system. For example:
# /usr/sbin/emxmgr -d
emx0 emx1 emx2
Use the emxmgr -m command to display an adapter’s target ID mapping.
For example:
# /usr/sbin/emxmgr -m emx0
emx0 SCSI target id assignments:
SCSI tgt id 0 : portname 5000-1FE1-0000-0CB2
nodename 5000-1FE1-0000-0CB0
SCSI tgt id 5 : portname 1000-0000-C920-A7AE
nodename 1000-0000-C920-A7AE
SCSI tgt id 6 : portname 1000-0000-C920-CD9C
nodename 1000-0000-C920-CD9C
SCSI tgt id 7 : portname 1000-0000-C921-0D00 (emx0)
nodename 1000-0000-C921-0D00
The previous example shows four Fibre Channel devices on this SCSI bus.
The Fibre Channel adapter in question, emx0, at SCSI ID 7, is denoted by
the presence of the emx0 designation.
Use the emxmgr -t command to display the Fibre Channel topology for
the adapter. For example:
# emxmgr -t emx1
emx1 state information:
1
Link : connection is UP
Point to Point
Fabric attached
FC DID 0x210413
Link is SCSI bus 3 (e.g. scsi3)
SCSI target id 7
portname is 1000-0000-C921-07C4
nodename is 1000-0000-C921-07C4
