13597 Solaris 8 and Solaris 10 clients can experience failover delays

When a Virtual NFS Service fails over to another server, a Solaris

10 client using TCP-based NFS mounts can pause for 80 to 90

seconds before I/O resumes normally. This delay is caused by a

client-side NFS RPC bug and applies only to NFS RPC over TCP.

UDP-based mounts are not affected. The problem can be

resolved by applying the recommended Sun patches for Solaris

10.

A similar problem exists on Solaris 8; however, it is significantly

rarer in occurrence and is not fixed by Sunʹs currently

recommended patches for Solaris 8. Delays of up to four

minutes may be experienced. Again, only TCP-based mounts

are affected. On Solaris 8, these delays can often be concluded by

running a command such as df on the client from a different

user session.

Solaris 9 does not have either of these issues.
