AIX with 2 Net Interfaces lose connectivity

hi guys

We have a AIX Server with TSM installed.
This server has en0 for administration purposes and we have en1 for backup stuff.

en0 subnet 10.10.10.x
en1 subnet 10.10.20.x

The issue we are having is all of a sudden the LPARs we are backing up lose connectivity to the AIX-TSM Server. for example
en1 ip is 10.10.20.10 and a TSM LPAR client that we are backing up is 10.10.20.11

Backup fails and we found that LPAR client 10.10.20.11 won't ping 10.10.20.10, but if go to the AIX-TSM server ping works and ping from LPAR client is back.

It's like ping from the AIX-TSM box reactivates connectivity.

Something important to mention we found the problem making backups but today we were doing to test and the connectivity is gone doing nothing and pinging from AIX-TSM server to LPAR Clients reactivates it

Anyone has seen an issue like this?

en0 is always fine

thanks a lot

NAME
ocf_pacemaker_ping - node connectivity SYNOPSIS
[OCF_RESKEY_pidfile=string] [OCF_RESKEY_dampen=integer] [OCF_RESKEY_name=string] [OCF_RESKEY_multiplier=integer] [OCF_RESKEY_host_list=string] [OCF_RESKEY_attempts=integer] [OCF_RESKEY_timeout=integer] [OCF_RESKEY_options=string] [OCF_RESKEY_failure_score=integer] [OCF_RESKEY_debug=string] ping [start | stop | reload | monitor | meta-data | validate-all] DESCRIPTION
Every time the monitor action is run, this resource agent records (in the CIB) the current number of ping nodes the host can connect to. It is essentially the same as pingd except that it uses the system ping tool to obtain the results. SUPPORTED PARAMETERS
OCF_RESKEY_pidfile = string [/ping-] PID file OCF_RESKEY_dampen = integer [5s] Dampening interval The time to wait (dampening) further changes occur OCF_RESKEY_name = string [pingd] Attribute name The name of the attributes to set. This is the name to be used in the constraints. OCF_RESKEY_multiplier = integer [] Value multiplier The number by which to multiply the number of connected ping nodes by OCF_RESKEY_host_list = string [] Host list The list of ping nodes to count. OCF_RESKEY_attempts = integer [2] no. of ping attempts Number of ping attempts, per host, before declaring it dead OCF_RESKEY_timeout = integer [2] ping timeout in seconds How long, in seconds, to wait before declaring a ping lost OCF_RESKEY_options = string [] Extra Options A catch all for any other options that need to be passed to ping. OCF_RESKEY_failure_score = integer [] failure_score Resource is failed if the score is less than failure_score. Default never fails. OCF_RESKEY_debug = string [false] Verbose logging Enables to use default attrd_updater verbose logging on every call. AUTHOR
