I run my TSM servers on Solaris 8. I use raw volumes built with Solstice DiskSuite (Solaris Volume Manager in Solaris 9). When I first brought TSM up on Solaris I put my db, logs and disk pools on UFS with logging and the performance was awful. Solaris 8 UFS is actually quite fast for most applications so I was rather surprised at the performance problem. I've never tried TSM using VxFS, I saw no need to. The performance with raw volumes is very good.
JFS is not native to Solaris, and I don't know of any way to use JFS on Solaris. If you want a journalled file system use VxFS or UFS with logging. With the improvements in DiskSuite I really can't see much reason to use Veritas. It's costly and for most environments only gives minimal performance improvements.
