SLB issue on 6860 switch

[Xavier]

Hello.

I tried to set SLB on omniswitch 6860 and 2 debian web servers.
The servers has been set as required on Omniswitch docs "Omniswitch Core Switching Page 388"

SLB01 192.168.81.246
SLB02 192.168.81.247

Loopback configured on both web servers:

ifconfig lo:1 192.168.81.245 broadcast 192.168.81.245 netmask 255.255.255.255

192.168.81.245 is the VIP

/etc/sysctl.conf file set also as required

net.ipv4.conf.eth0.arp_ignore=1
net.ipv4.conf.eth0.arp_announce=2

SLB set on the 6860 omniswitch:

ip slb admin-state enable
ip slb server ip 192.168.81.246 cluster TestApache
ip slb server ip 192.168.81.247 cluster TestApache

The 2 web servers still in "discovery" mode:

Cluster TestApache
VIP : 192.168.81.245,
Type : L3,
Admin status : Enabled,
Operational status : Out of Service,
Ping period (seconds) = 60,
Ping timeout (milliseconds) = 3000,
Ping retries = 3,
Probe = None,
Number of packets = 0,
Number of servers = 2,
Hash type = ECMP
Server 192.168.81.246
Admin status = Enabled, Operational status = Discovery,
Weight = 1, Availability (%) = 0
Server 192.168.81.247
Admin status = Enabled, Operational status = Discovery,
Weight = 1, Availability (%) = 0

The omniswitch could ping both web servers.

Could you confirm SLB compatible with Virtual Machine and Debian OS?

If yes, please, could you help me to set the SLB or Debian servers?

Best regards.

Xavier.
