Starting SCSI LUN Discovery
SCSI LUN discovery is done on demand.
Only Nx ports present in the name server database and that are registered as FC4 Type = SCSI_FCP are
discovered.
To begin SCSI LUN discovery, follow this step:
Command
Step 1
switch# discover scsi-target local os all
discovery started
switch# discover scsi-target remote os aix
discovery started
switch# discover scsi-target vsan 1 fcid 0x9c03d6
discover scsi-target vsan 1 fcid 0x9c03d6
VSAN:
00:00:00:00:00:00:00:00
PRLI RSP: 0x01 SPARM: 0x0012
SCSI TYPE: 0 NLUNS: 1
Vendor: Company 4 Model: ST318203FC
Other: 00:00:02:32:8b:00:50:0a
switch# discover scsi-target custom-list os linux
discovery started
Configuring SCSI Target Discovery
Automatic-global SCSI target discovery is enabled by default. However, you can configure discovery so
that it is triggered for specific VSANs using on-demand, name server polling, or auto-polling options.
All options are on by default. Use the no scsi-target discovery command to turn off all discovery
options.
Example 23-1 Configuring SCSI Target Discovery
switch# config t
switch(config)# scsi-target discovery
Example 23-2 Configuring SCSI Target Auto-Polling Discovery for VSAN 1
switch# config t
switch(config)# scsi-target auto-poll vsan 1

Initiating Customized Discovery

Customized discovery consists of a list of VSAN and domain pairs that are selectively configured to
initiate a discovery. Use the custom-list option to initiate this discovery. The domain ID is a number
from 0 to 255 in decimal or a number from 0x0 to 0xFF in hex.
To initiate a customized discovery, follow this step:
