Error description
After an initial mount of an NFSv4 filesystem on AIX, the lease time of the NFSv4 server is saved off. If all the filesystems from this NFSv4 server are unmounted (on the client), and the lease time changed on the server, the new lease time value is not used by the AIX client. It'll continue to use the old value. This will result in the lease renew operations to not happen within time, and causes the lease to expire. The NFSv4 server could fail delegations and locks if leases expire.
Local fix
Reboot AIX client after the lease time on the NFSv4 server has been changed.
Problem summary
AIX NFSv4 Client will not update the lease time if NFSv4 server changes the lease.
Problem conclusion
update the lease time every time we try to get a server object.
Temporary fix
