samsharefs -u -R [QFS share name]

Problem: changed the host ip and now not able to mount a QFS file system

server old ip : 1.10.10.1
server new ip: 10.1.1.1

Getting an error:
SC_mount() error: Transport endpoint is not connected

samshare -R shows old ip address of the server 

# samsharefs -u -R 
#
# Host file for family set 'share1'
#
# Version: 4    Generation: 18    Count: 6
# Server = host 0/titan, length = 192
#
1.10.10.1 1 0 server
1.10.10.2 2 0
1.10.10.3 3 0

Solution:
samsharefs -u -R

# samsharefs -u -R 
#
# Host file for family set 'share1'
#
# Version: 4    Generation: 18    Count: 6
# Server = host 0/titan, length = 192
#
10.1.1.1 1 0 server
10.1.1.2 2 0
10.1.1.3 3 0

 This procedure allows you to add a new client or to change IP addresses or add secondary servers.

Edit the file /etc/opt/SUNWsamfs/hosts. on the server to add the new client, change IP addresses or make any other change to the configuration of the file system.

Update the binary hosts file on the server:

samsharefs -u

if the file system is mounted OR

samsharefs -u  -R

if the file system is unmounted (counterintuitive, but correct).

Removing a client requires that you unmount the file system on the server, which means you must first unmount all clients. It is possible to unmount and unconfigure the client, then to do the server unconfiguration during scheduled downtime. Leaving the client in the configuration is a security hole, however, so it should be removed as soon as possible.
