1. Using fcinfo

In Solaris 10, you can use the “fcinfo” utility which is a 2 step process to identify the Luns presented to the server.

1. Find the HBA port WWN number on the server:

# fcinfo hba-port

This command will show the HBA Port WWN among other information like the Node WWN, Device name, manufacturer, firmware, driver details etc.

root@myserver:/root # fcinfo hba-port
HBA Port WWN: 21000022ff0553e9
OS Device Name: /dev/cfg/c5
Manufacturer: QLogic Corp.
Model: 371-4324-02
Firmware Version: 05.03.02
FCode/BIOS Version: BIOS: 2.02; fcode: 2.03; EFI: 2.01;
Serial Number: 0402R00-1102885753
Driver Name: qlc
Driver Version: 3.00p
Type: L-port
State: online
Supported Speeds: 2Gb 4Gb 8Gb
Current Speed: 4Gb
Node WWN: 20000022ff0553e9

Here 21000022ff0553e9 is the WWN number for the HBA port.

2. List SCSI targets for the remote port attached to the HBA port attached to the above.

# fcinfo -sl -p HBA-Port-WWN

root@myserver:/root # fcinfo remote-port -sl -p 21000022ff0553e9
Remote Port WWN: 202400a0b8744072
Active FC4 Types:
SCSI Target: yes
Node WWN: 200400a0b8744072
Link Error Statistics:
Link Failure Count: 1
Loss of Sync Count: 2
Loss of Signal Count: 72
Primitive Seq Protocol Error Count: 0
Invalid Tx Word Count: 0
Invalid CRC Count: 0
LUN: 0
Vendor: SUN
Product: LCSM100_F
OS Device Name: /dev/rdsk/c5t202400A0B8744072d0s2
LUN: 2 Vendor: SUN
Product: LCSM100_F
OS Device Name: /dev/rdsk/c5t202400A0B8744072d2s2
LUN: 31 Vendor: SUN
Product: Universal Xport
OS Device Name: /dev/rdsk/c5t202400A0B8744072d31s2

Here, LUN0 and LUN2 are the actual disks and LUN31 is the Command device for the Storage controller

2. Using cfgadm

You can also find the above information using the “cfgadm” utility. One of the following commands should reveal the LUNS attached to the controller. Although the later works only on Solaris 10.

# cfgadm -al -o show_FCP_dev c5
 
or
 
# cfgadm -al -o show_SCSI_LUNS c5

where c5 is the controller. If you do not mentioned the controller, it then displays for every single disk controller on the server.

root@myserver:/root # cfgadm -al -o show_FCP_dev c5
Ap_Id Type Receptacle Occupant Condition
c5 fc-private connected configured unknown
c5::202400a0b8744072,0 disk connected configured unknown
c5::202400a0b8744072,2 disk connected configured unknown
c5::202400a0b8744072,31 disk connected configured unknown

root@myserver:/root # cfgadm -al -o show_SCSI_LUN c5
Ap_Id Type Receptacle Occupant Condition
c5 fc-private connected configured unknown
c5::202400a0b8744072,0 disk connected configured unknown
c5::202400a0b8744072,2 disk connected configured unknown
c5::202400a0b8744072,31 disk connected configured unknown

Share your thoughts, if you know more ways of doing this.

Talking about the WWN names, there are also

World Wide port Name (WWpN), a WWN assigned to a port on a Fabric which is what you would be looking for most of the time.

World Wide node Name (WWnN), a WWN assigned to a node/device on a Fibre Channel fabric.

To find the WWN numbers of your HBA card in Sun Solaris, you can use one the following procedures

Using fcinfo (Solaris 10 only)

This is probably the easiest way to find the WWN numbers on your HBA card. Here you can see the HBA Port WWN (WWpN) and the Node WWN (WWnN) of the two ports on the installed Qlogic HAB card.

This is also useful in finding the Model number, Firmwar version FCode, supported and current speeds and the port status of the HBA card/port.

root@ sunserver:/root# fcinfo hba-port | grep WWN
HBA Port WWN: 2100001b32xxxxxx
Node WWN: 2000001b32xxxxxx
HBA Port WWN: 2101001b32yyyyyy
Node WWN: 2001001b32yyyyyy

For detailed info including Make & model number, Firmware, Fcode and current status and supported/current speeds then

root@ sunserver:/root# fcinfo hba-port
HBA Port WWN: 2100001b32xxxxxx
OS Device Name: /dev/cfg/c2
Manufacturer: QLogic Corp.
Model: 375-3356-02
Firmware Version: 4.04.01
FCode/BIOS Version:  BIOS: 1.24; fcode: 1.24; EFI: 1.8;

Current Speed: 4Gb
Node WWN: 2000001b32xxxxxx
HBA Port WWN: 2101001b32yyyyyy
OS Device Name: /dev/cfg/c3
Manufacturer: QLogic Corp.
Model: 375-3356-02
Firmware Version: 4.04.01
FCode/BIOS Version:  BIOS: 1.24; fcode: 1.24; EFI: 1.8;
Type: unknown
State: offline
Supported Speeds: 1Gb 2Gb 4Gb
Current Speed: not established
Node WWN: 2001001b32yyyyyy

Using scli

root@ sunserver:/root# scli -i | egrep “Node Name|Port Name”
Node Name                  : 20-00-00-1B-32-XX-XX-XX
Port Name                  : 21-00-00-1B-32-XX-XX-XX
Node Name                  : 20-01-00-1B-32-YY-YY-YY
Port Name                  : 21-01-00-1B-32-YY-YY-YY

For more detailed info on the HBA Cards run as follows: Similar to fcinfo but also provides Model Name and serial number.

root@ sunserver:/root# scli -i

Using prtconf

root@ sunserver:/root# prtconf -vp | grep -i wwn
port-wwn:  2100001b.32xxxxxx
node-wwn:  2000001b.32xxxxxx
port-wwn:  2101001b.32yyyyyy
node-wwn:  2001001b.32yyyyyy

Using prtpicl

root@ sunserver:/root# prtpicl -v | grep wwn
:node-wwn  20  00  00  1b  32  xx  xx  xx
:port-wwn  21  00  00  1b  32  xx  xx  xx
:node-wwn  20  01  00  1b  32  yy  yy  yy
:port-wwn  21  01  00  1b  32  yy  yy  yy

Using luxadm

Run the following command to obtain the physical path to the HBA Ports

root@ sunserver:/root$ luxadm -e port
/devices/pci@400/pci@0/pci@9/SUNW,qlc@0/fp@0,0:devctl              CONNECTED
/devices/pci@400/pci@0/pci@9/SUNW,qlc@0,1/fp@0,0:devctl            NOT CONNECTED

With the physical path obtained from the above command, we can trace the WWN numbers as follows. here I use the physical path to the one that is connected:

root@ sunserver:/root$ luxadm -e dump_map /devices/pci@400/pci@0/pci@9/SUNW,qlc@0/fp@0,0:devctl
Pos  Port_ID Hard_Addr Port WWN         Node WWN         Type
0    123456  0         1111111111111111 2222222222222222 0×0  (Disk device)
1    789123  0         1111111111111111 2222222222222222 0×0  (Disk device)
2    453789  0         2100001b32xxxxxx 2000001b32xxxxxx 0x1f (Unknown Type,Host Bus Adapter)

Hope this helps. If you know of any more way then please feel free to post it to the comments and I shall amend it to the article.
