The document provides instructions for installing and configuring new storage LUNs on a Solaris system. It includes steps to install required OS packages, check that the HBAs are detected, collect information about existing LUNs, assign new LUNs, format and mount the LUNs, and configure Veritas (if used) to recognize the new LUNs.
![cfgadm -c configure c1
cfgadm -c configure c2
It does not effect previously configured LUNs.
If they do not, a few things to try if LUNs don’t show up
Check for legacy txt in sd.conf. Solaris 10 does not need this, and it just slows up
booting.
Text in this file “my theory is” can mess finding new LUNs in Solaris 10.
Update sd.conf
vi /kernel/drv/sd.conf
Add new LUN IDs created on Hitachi
After Solaris 9, this should not be needed. 10 does not need this.
Instruct Solaris to re-read sd.conf
update_drv -f sd
9 and 10 can do this. 8 will failed.
Scan scsi bus so Solaris can see the new luns
devfsadm
Find new LUNs
cfgadm -al -o show_SCSI_LUN
(Note added LUNS when available will be seen here as "unconfigured"
If LUNs do not appear, server reboot will be needed.
reboot -r
Create Label for LUN
This is all only valid if you Are Not running Veritas
Now run a format command
# Note: the disk only needs to be labeled on once. The following servers only need
mount it
Run format command
format
A disk looking like the following should show up.
c6t600A0B800021E8B90000536B456B26B3d0
/scsi_vhci/ssd@g600a0b800021e8b90000536b456b26b3
Select the disk number. It will need a volume name if it does not already have one.
Since this is the Export directory for Solaris "export" is a good volume name. Solaris
does
not like disks without a volume name (label).
Some commands in format to look at are:
format> current
Current Disk = c6t600A0B800021E8B90000536B456B26B3d0
/scsi_vhci/ssd@g600a0b800021e8b90000536b456b26b3
(SUN and Solaris see this as a known disktype)
format> type
select type 19
format>volname
Enter 8-character volume name (remember quotes)[""]:"export"
Ready to label disk, continue?y
format> save
Saving new disk and partition definitions
Enter file name["./format.dat"]:
format> quit
This only needs to be done from one machine

Add and configure lu ns in solaris
- 1. Ensure the following OS packages/patches are installed This one should be on the first Solaris install DVD SUNWqlc These two dowload from SUN if needed 120965-01 119131-13 # Note: If HBA's are in server when Solaris is installed these should all have been installed VIEW HBA’s: Once the OS is updated and a reboot -- -r has been done check if SUN/Solaris is seeing the HBA's. Run the luxadm command: luxadm -e port Example: 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 Above is showing two HBA's 2 and 2,1 OK, good to go. Before assigning LUN’s Collect Current HBA information fcinfohba-port -l |grep HBA HBA Port WWN: 210000e08b1c829a HBA Port WWN: 210000e08b1c2395 Collect LUNs Solaris already knows about fcinfo remote-port -sl -p 210000e08b0c5518 > 210000e08b0c5518.out fcinfo remote-port -sl -p 210100e08b2c5518 > 210100e08b2c5518.out cfgadm -al -o show_SCSI_LUN>currentLUNs.out (Note added LUNS when available will be seen here as "unconfigured" Scan deeply LUNs attached to each HBA This shows HBA’s luxadm -e port /devices/pci@1c,600000/pci@1/SUNW,qlc@4/fp@0,0:devctl CONNECTED /devices/pci@1c,600000/pci@1/SUNW,qlc@5/fp@0,0:devctl CONNECTED Run following command on each Controller luxadm -e dump_map /devices/pci@1c,600000/pci@1/SUNW,qlc@4/fp@0,0:devctl luxadm -e dump_map /devices/pci@1c,600000/pci@1/SUNW,qlc@5/fp@0,0:devctl Assigning LUN’s Now is the time to assign LUNs Assign LUNs. Configure New LUN’s on Solaris LUNS should “Just Show Up” on Solaris 10. Cgfadm –al Example output c1::2200000c50401277 disk connected unconfigured unknown New LUNs show as unconfigured until cfgadm is used. When LUNs appear configure them cfgadm -c c1::2200000c50401277 Also command can be done globally for each controller:

- 3. run the luxadm command to get LUN info luxadm probe Example: root@j2-apps01 # 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 Each server will have a different Path, to the same LUN Create New Filesystem on LUN/Volume Now create a new filesystem (format) Run newfs command on LUN found in luxadm probe command: newfs /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2 Example: root@j2-apps01 # newfs /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2 newfs: construct a new filesystem /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2: (y/n)? y /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2: 1073676288 sectors in 32766 cylinders of 512 tracks, 64 sectors 524256.0MB in 10922 cyl groups (3 c/g, 48.00MB/g, 5824i/g) super-block backups (for fsck -F ufs -o b=#) at: 32, 98400, 196768, 295136, 393504, 491872, 590240, 688608, 786976, 885344, Initializing cylinder groups: ............................................................................... ............................................................................... ............................................................ super-block backups for last 10 cylinder groups at: 1072703520, 1072801888, 1072900256, 1072998624, 1073096992, 1073195360, 1073293728, 1073392096, 1073490464, 1073588832, Now the disk is mountable and solaris can understand it This only needs to be done from one machine A LUN is a physical disk to Solaris at this point Edit /etc/vfstab to mount the new LUN Now edit /etc/vfstab to mount the new LUN The new LUN/disk in this example (from luxadm) is c6t600A0B800021E8B90000536B456B26B3d0s2 The device path is: /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2 Add the folling line to /etc/vfstab: /dev/dsk/c6t600A0B800021E8B90000536B456B26B3d0s2 /dev/rdsk/c6t600A0B800021E8B90000536B456B26B3d0s2 /export/home ufs 1 yes logging Edit this to match LUN ID of your system This will mount at boot Run mount command to test if LUN mounts: mount /export/home There is no output if it works Run the mount command again to see new LUN and mount point mount Example: root# mount |grep export
