Hi,
Thanks to Casper Dik for promptly responding.
The answer to the question below is Yes.
For some info on UFS filesystems, here is Caspers e-mail:

Hi All,
I was asked the following question and would appreciate your comments. In
my opinion it should be no problem.
I will summarize.
"I have a Sybase ASIQ 12.5.3 running on Solaris 2.6. The Sybase Database was
using raw datafiles. I detached all the Sybase disks and installed Solaris
9. I then attached the Sybase disks and started Sybase and all seems fine.
The database status is good, I can do a Sybase backup and I can insert
records.
My question is: Could I do the same if the database uses mounted file
systems? i.e. Are there any differences in the file systems from 2.6 to 9 if
the file systems are defined as ufs?"
Regards,
Alan.
