SAN boot disk in a cluster node?

As far as I remember, SC requires local boot disk.

Is it possible to use the SAN boot disk? Can this configuration work being just not supported by SUN or there is some technical limitation ?

I am thinking of low price configuration with two diskless X2100s + HBAs and SAN storage. Possible?

thanks

The rule for boot disks gos like this:

Any local storage device, supported by the base platform as a boot device, can be used as a boot device for the server in the cluster as well. A shared storage device cannot be used as a boot device for a server in a cluster. It is recommended to mirror the root disk. Multipathed boot is supported with Sun Cluster when the drivers associated with SAN 4.3 (or later) are used in conjunction with an appropriate storage device (i.e. the local disks on a SF v880 or a SAN connected fiber storage device).

So your boot disk can be in a SAN as long the base platform supports it as a boot disk and it is not configured as a shared lun in the SAN (i.e. visible to other nodes than the one that uses it as boot disk).

You need to check the support matrix of the storage device you plan to use, if it is supported as a boot device for the X2100 + HBA. If the answer is yes, you just must make sure that this lun is only visible to that X2100.
