Solaris Maximum LUN Size

The 'sd' driver can handle a maximum LUN size of 1TB. The EFI label is required for larger luns. It is available beginning with later releases of Solaris 9.

The scsi driver can handle a maximum LUN offset of 2TB until Solaris 10 update 1 (01/06).

So Solaris 8 is simple: 1TB.

Having just tried, I don't think you can stitch together LUNs with SVM to be larger than 1TB on Solaris 8.

Solaris 9 has a brace of patches (Solaris 10 has only a handfull) that get you to handle multi-terabyte filesystems, volumes, metadevices, etc. (of course, you need a 64-bit x86 or SPARC kernel to be able to do that and Solaris 9 didn't have 64-bit x86) so I'd expect it to work, though I haven't tried.

If you can get access (i.e. have a SPECTRUM contract or similar), look up document id 82575 on SunSolve, "Solaris[TM] Operating System: List of Multi-terabyte related patches."
