Configure EMC Powerpath?
Hi ,
I have a redhat 5.3 server which has 2 vg.. one is rootvg in local harddisk and another one is applicationvg in SAN.. When I reboot the server , EMC powerpath driver is not starting up automatically. Hence applicationvg is not mounting properly. Therefore I need to unmount it manually and then I can get into system.
1.How do I start up emc powerpath driver automatically... ?
I did lsmod and restart the service.. still it gives the same problem...
I thought of uninstall and reinstalling the emc powerpath and reconfigure the whole thing... is that good idea???
If so, How do i configure the EMC Powerpath?

writesrv
writesrv(8) System Manager's Manual writesrv(8)
NAME
writesrv - Lets users send messages to and receive messages from a remote system.
SYNOPSIS
/usr/sbin/writesrv
DESCRIPTION
The writesrv daemon allows users to send messages to users on a remote system, and to receive responses from users on a remote system with
the write command.
The writesrv command receives incoming requests from a write command and creates a server process to handle the request. This server
process communicates with the client process (write) and provides whatever services are requested.
To perform these services, the writesrv daemon creates a socket on the port defined in the /etc/services file. All requests for service go
as messages to this socket.
STARTING AND STOPPING writesrv.
You can cause the writesrv daemon to be started during system boot with /sbin/init.d/write. The writesrv daemon starts automatically if the
WRITESRV variable is defined properly in /etc/re.config. To start writesrv automatically during system boot, do the following as superuser.
rcmgr set WRITESRV yes
To prevent writesrv from starting automatically during system boot, do the following as superuser:
rcmgr set WRITESRV no
By default, writesrv is not set and therefore /usr/sbin/writesrv does not run.
You can start the writesrv daemon manually as follows:
/sbin/init.d/write start
You can stop writesrv manually as follows:
/sbin/init.d/write stop
NOTES
If the writesrv daemon terminates abnormally (that is, for a system crash, a power failure, or the kill -9 command), someone must manually
clean out the /usr/spool/writesrv directory to remove any files left behind.
