Scanning LUN on Solaris and Mount

Here are the steps to scanning LUN's on Solaris and Mount

Step 1: Display HBA's

example:
bash-3.00# luxadm -e port
/devices/pci@1d,700000/SUNW,qlc@2,1/fp@0,0:devctl CONNECTED
/devices/pci@1d,700000/SUNW,qlc@2/fp@0,0:devctl CONNECTED

In the above instance it is displaying 2 HBA's

Step 2: Get the WWN for HBA's

bash-3.00# fcinfo hba-port -l |grep HBA
HBA Port WWN: 21000024ff295a34
HBA Port WWN: 21000024ff295a35

Step 3:

            i) Get LUNs Solaris OS already knows about

bash-3.00# fcinfo remote-port -sl -p 21000024ff295a34 > 21000024ff295a34.out
bash-3.00# fcinfo remote-port -sl -p 21000024ff295a35 > 21000024ff295a35.out
bash-3.00# cfgadm -al -o show_SCSI_LUN > currentLUNs.out

           ii) To get additional information such as link statistics on HBA

bash-3.00# fcinfo hba-port -l 21000024ff295a35
HBA Port WWN: 21000024ff295a35

bash-3.00#

Step 4: For each entry in /dev/fc, issue a "luxadm -e dump_map" command to view all the devices that are visible through that HBA port or for a specific HBA's

bash-3.00# luxadm -e port
/devices/pci@1d,700000/SUNW,qlc@2,1/fp@0,0:devctl CONNECTED
/devices/pci@1d,700000/SUNW,qlc@2/fp@0,0:devctl CONNECTED

bash-3.00# luxadm -e dump_map /devices/pci@1d,700000/SUNW,qlc@2,1/fp@0,0:devctl
bash-3.00# luxadm -e dump_map /devices/pci@1d,700000/SUNW,qlc@2/fp@0,0:devctl

Step 5: Let map a LUN from a storage system to solaris host and the scan

bash-3.00# devfsadm #This will scan for LUN but in solris 10 LUN should be populated automatically

bash-3.00# cfgadm -al #New LUNs show as unconfigured

Example:
c1::2200000c50401277 disk connected unconfigured unknown

Step 6: Configure the LUN using "cfgadm"

bash-3.00# cfgadm -c c1::2200000c50401277

bash-3.00# cfgadm -c configure c1 # We can also do it at controller level
bash-3.00# cfgadm -c configure c2

Troubleshooting:

 i) If LUNS are still not visible to solaris host

• Add a LUN id to /kernel/drv/sd.conf ( This is a text file ) using your comfortable editor
• Then "update_drv -f sd", Solaris 9 and 10 does not required this step
• Then scan for the LUN "devfsadm"

bash-3.00# vi /kernel/drv/sd.conf # Add LUN id
bash-3.00# update_drv -f sd"
bash-3.00# devfsadm

ii) If still not working then reboot the host

bash-3.00# reboot -r

Step 7: Get LUN info for Mounting by run the luxadm command

bash-3.00# luxadm probe
No Network Array enclosures found in /dev/es
Found Fibre Channel device(s):
Node WWN:200400a0b821eab1 Device Type:Disk device
Logical Path:/dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2

Step 8: Label disk using format command and select respective drive from luxadm output

Step 9 : Create New Filesystem on the LUN

bash-3.00# newfs /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2

Step 10: Edit /etc/vfstab to auto mount the new LUN on reboot

bash-3.00# vi /etc/vfstab # The content below in the double quotes show be in one line
"/dev/dsk/c6t600A0B800021E8B90000536B456B26B3d0s2 /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2 /tibco ufs 1 yes logging"

Step 11: You can manually mount it using following commands

bash-3.00# mount /tibco

Step 12: Verfing the mount point

bash-3.00# mount | grep tibco

/tibco on /dev/dsk/c6t600A0B800021E8B90000536B456B26B3d0s2 read/write/setuid/devices/intr/largefiles/logging/xattr/onerror=panic/dev=1d80022

Step 13: You are done ... Start writing files to the disk
