Connecting NetApp to Solaris Host over Fibre Channel

Once you have completed FC zoning, you are ready for host and target connectivity. Here is the step by step procedure: 

Download relevant (solaris 10) NetApp toolkit and copy it to /var/opt
Go to # /var/opt/
#pkgadd -d ./NTAPSANTool.pkg
#/opt/NTAP/SANToolkit/bin/basic_config -ssd_set
Enter Y
Now run
#stmsboot -D fp-e (this req a reboot as well)(To enable ISCSI multipatching on Fiber Cable)
init 6
After the machines comes back, run to check the output of all raw disks!!
#stmsboot-L (To display the names under the Solaris Multipathing)
To configure ALUA for SAN LUNs
# /opt/NTAP/SANToolkit/bin/mpxio_set -d
then reboot
again check
# stmsboot –L or devfsadm –C  (if  Solaris  I/O  multipathing  is not enabled, then no mappings are displayed, also check ALUA on SAN igroups it must be enable for mpxio)
To check the details of HBAs
# cd /opt/NTAP/SANToolkit/bin/
#    ./sanlunfcp show adapter -v
To show luns
#   ./sanlunlun show
# mpathadm list lu
* Here you will find 2 / 4 paths to storage on the basis of this assumption that each node has one / two FC paths to one / two SAN Switches. (Here we were shown 4 paths because we had 2 HBA’s)
Connect with root credentials
Luns require formatting, partitioning and labeling as given in the following procedure:-
Specify disk (enter its number): 1
format> p  (Press ‘p’ to ‘print’ the menu)
format> p (Select the partition option by pressing ‘p’)
partition> p (This will print the partition menu)
partition> 0 (Assign 48Mb to root slice’0’)
partition> p (Check the assigned partition)
partition> 1 (Set starting cylinder and partition size to 0)
partition> p (Check the slice if it is 0)
In the similar fashion turn the size to 0 of all rest of the slices
partition> 6
Enter partition id tag[unassigned]:
Enter partition permission flags[wm]:
Enter new starting cyl[0]: 3 (as first root slice is from cylinder  0-2, this will differ if the lun is of different size, please exercise caution )
Enter partition size[0b,0c,3e,0.00mb,0.00gb]: $ (The $ will issue all the saved space to this slice)
partition> p(Now check the partition table and null all the slices except slice 0 and 6)
partition> label (Press ‘yes’ and do the same labeling step on the other nodes in the cluster)
