I am new to this forum and want an urgent help from you experts. I am currently using SunOs 5.10.
I have a .cfi file which contains some commands to be executed in a node(MSC node in telecom) To connect to a node (for eg node name is MSC1) we have a shell script that has the following command
(cfi utility is invoked from /bin, -F option followed by the path of file.cfi which contains the commands, -N connects to the network element MSC1 and the o/p is stored in outputfile)
there are many lines like this for connecting into different nodes in the script file.
Now the trouble is sometimes due to network issues the connection to the nodes(MSC1 in this case) is not obtained and the execution moves into the next line in the script.So that particular node is missed and results in missing data. I want to retry to the node after some time when all the lines have been performed.
there is an option -b in cfi help list (tries after a delay) but the problem is if i use -b option it gets stuck onto that particular line/Node only and does not proceed to other commands until the connection is obtained and the work is done.
Please help me out how to come out of this situation urgently. I am a newbie to shell scripting.

lamnodes
LAMNODES(1) LAM TOOLS LAMNODES(1)NAME
lamnodes - Resolve LAM node/CPU notation to Unix hostnames.
SYNOPSIS
lamnodes [-chin] [where]
OPTIONS -c Suppress printing the CPU count for each node.
-h Print the command help menu.
-i Print IP addresses (instead of IP names)
-n Suppress printing CPU count for each node
DESCRIPTION
The lamnodes command is used to resolve LAM node/CPU nomenclature to Unix hostnames. It can be used to determine the current running con-
figuration of the LAM/MPI run-time environment, and generate a boot schema that can be used to launch LAM in the future.
By default, lamnodes will print out the node number, default IP name, CPU count, and per-node flags for each node in the running LAM.
gethostbyaddr(3) is used to obtain default hostnames. If gethostbyaddr(3) fails, the IP number is displayed instead.
This command can be used by setup shell scripts (and the like) to determine information from a currently-running LAM universe. For exam-
ple, use lamnodes to resolve particular CPUs and/or nodes to specific unix hostnames. In a batch environment, lamnodes can be used to
determine which CPUs share a common node (note that MPI_GET_PROCESSOR_NAME can be used for a similar effect in an MPI program).
lamnodes also shows per-node flags. Currently defined flags are:
origin The node where lamboot was executed.
this_node The node where lamnodes is running.
no_schedule The node will not be used to run MPI and serial processes when N and C are used to mpirun and lamexec.
EXAMPLES
lamnodes N -n
Display IP names and CPU counts for all nodes. This output can be saved and later used with lamboot(1).
lamnodes C -n -c
Display the IP name of the nodes containing each CPU, and suppress the LAM node number and CPU count. This output can be saved and
later used with lamboot(1).
