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?

automountd
automountd(1M) automountd(1M)
NAME
automountd - autofs mount/unmount daemon
SYNOPSIS
name=value]
DESCRIPTION
is an RPC server that answers file system mount and unmount requests from the filesystem. It uses local files or name service maps to
locate filesystems to be mounted. These maps are described with the command (see automount(1M)).
The daemon is automatically invoked if the variable is set to 1 in
Options
Trace. Expand each
RPC call and display it to
Verbose. Log status messages to
Turn off browsing for all
mount points. This option overrides the map option on the local host.
Force all mounts to the local host to be NFS mounts instead of
the default LOFS mounts. This is necessary for highly available NFS mounts.
Assign value to the indicated map substitution variable. These assignments cannot be used to substitute variables in the master
map
Tracing
While is running, the signal can be sent to to turn tracing on. It logs messages in To turn tracing off, send the signal again.
RETURN VALUE
returns:
0 successful
1 failure
EXAMPLES
To turn on tracing, enter:
or
No messages are displayed by the trace. Check the results in
WARNINGS
Any filesystems that are being managed by should never be manually mounted or unmounted. Even if the mount or unmount operation appears to
complete successfully, the resulting change of state to the managed filesystem can lead to disruptive or unpredictable results, including
but not limited to: commands hanging or not returning expected results, and applications failing due to their dependencies on those mounted
filesystems. A reboot may be necessary to resolve these issues.
