Ensuring That LUN Level Information Is Visible
▼
To Ensure LUN Level Information is Visible
Use the cfgadm command to identify LUN level information.
If you issue the cfgadm -al -o show_SCSI_LUN controller-ID command immediately after a
system boots up, the output might not show the Fibre Channel Protocol (FCP) SCSI LUN level
information. The information does not appear because the storage device drivers, such as the
ssd and st driver, are not loaded on the running system.
Use the modinfo command to check whether the drivers are loaded. After the drivers are loaded,
the LUN level information is visible in the cfgadm output.

To Detect Fabric Devices Visible on a Host
This section provides an example of the procedure for detecting fabric devices using FC host
ports c0 and c1. This procedure also shows the device conguration information that is
displayed with the cfgadm(1M) command.
Note – In the following examples, only failover path attachment point IDs (Ap_Ids) are listed.
The Ap_Ids displayed on your system depend on your system conguration.
Loginasroot(su - root).
Display the information about the attachment points on the system.
# cfgadm -l
Ap_Id Type Receptacle Occupant Condition
c0 fc-fabric connected unconfigured unknown
c1 fc-private connected configured unknown
In this example, c0 represents a fabric-connected host port, and c1 represents a private,
loop-connected host port. Use the cfgadm(1M) command to manage the device configuration
on fabric-connected host ports.
By default, the device conguration on private, loop-connected host ports is managed by a host
using the Solaris 10 OS.
Display information about the host ports and their attached devices.
# cfgadm -al
Ap_Id Type Receptacle Occupant Condition
c0 fc-fabric connected unconfigured unknown
c0::50020f2300006077 disk connected unconfigured unknown
c0::50020f23000063a9 disk connected unconfigured unknown
c0::50020f2300005f24 disk connected unconfigured unknown
