The internal disks in a V880 are on an internal loop, and cannot participate in the SAN.
As for configuring the "SAN", that depends on the actual storage array, switches, & HBA's that you have. Generally speaking you will need to format the parity groups into LDEV's, run fiber, present LUN's to a port, configure LUN security, then configure the zones on the switch. Then assuming you are using Sun HBA's (QLogic) with the leadville drivers, you `cfgadm -c configure c# c#` the controllers, and put a VTOC on the disks.
You can use either Veritas Volume Manager and file system, or Veritas storage foundation for Oracle which also comes in an HA flavor (VCS). Veritas brings some flexibility, simplicity, and performance, but is expensive. Sun Disk Suite (SDS) and the ufs file system ship with Solaris.
If you are hardware RAID 10 on your array, I would use concatonated volumes. I usually put the ORACLE_BASE/HOME undert /app/oracle, and put the database under /u01 thru /u05, and use /u06 for archive logs. If I need a local slice for backups, I put it at /app/backups.
If using vxfs, make sure to use the largest block size that equals or is a multiple of your db/tablespace block size.
All of my V880's only have 6 internal 72GB disks. I usually use two for the OS mirrored with SDS, and the other four for rootdg with pre 4.0 vxvm. With 4.x, I make them a disk group, and would put your Oracle binaries and indexes on those disks, and the rest of the database on the SAN.
Realize that if you put disks on the SAN and the internal disks in the same disk group/set, you may have errors on boot or in single user because the drivers for the SAN HBA's have not loaded, and only part of the disk group will be visible.
Be sure to put noatime as a mount option in the vfstab, and if using ufs, also logging.

Hi everyone,
I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?

we have a hardware error on a 36GB HDD within a SunFire V880.
Disk seems to be really dead, cause changing the slot of the disk, moves the error along.

mkqdisk
mkqdisk(8) Quorum Disk Management mkqdisk(8)
NAME
mkqdisk - Cluster Quorum Disk Utility
WARNING
Use of this command can cause the cluster to malfunction.
SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]]
DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.
OPTIONS
-c device -l label
Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device
as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one
device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough
space to hold a UUID created with uuidgen(1).
-f label
Find the cluster quorum disk with the given label and display information about it.
-L Display information on all accessible cluster quorum disks.
-d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect.
