Re: Rép. : Setting IP redunduncay in AS/400



fixed

Yes, you could since LINETH02 has it's own IP adress.

We use Vision and what we do here is:
Create a second Virtual IP for Vision (or Itera in your case).
Link it to the same phisical interface, but in reverse order (user are routed to LINETH01 and Vision to LINETH02 when everything is nomal) If one interface fails, both traffic will go to the same physical interface, but still trough different virtual ones.

if we would do this....
could you still route mimix or iTera traffic to a specific line (in the
example below "LINETH02")?

all other traffic (http, telnet, ftp, odbc/jdbc) could point to virtual?

would it make sense to do so?

We do this using "proxy ARP"

First create the 2 actual interface:
ADDTCPIFC INTNETADR('x.x.x.x') LIND(LINETH01) SUBNETMASK('x.x.x.x') LCLIFC(‘y.y.y.y’)
ADDTCPIFC INTNETADR('x.x.x.x') LIND(LINETH02) SUBNETMASK('x.x.x.x') LCLIFC(‘y.y.y.y’)

Then create the virtual IP adress (this is the one that will get used by users ans linked to your DNS):
ADDTCPIFC INTNETADR('y.y.y.y') LIND(*VIRTUALIP) SUBNETMASK('255.255.255.255')

Then you activate the proxy ARP using the navigator:
- You go to Network/TCPIP configuration/IPv4/Interface
- right click on the virtual interface and select Properties
- selcect Advanced
- Activate the proxy ARP protocol (the interface must be varied off to be able to do this)

Finnaly, you must link the physical interface with the virtual one:
- You go to Network/TCPIP configuration/IPv4/Interface
- right click on the virtual interface and select Properties
- selcect Advanced
- Choose among the available inetrface and add them to prefered

The wording may not be exact (our systems are in french) but those are the main steps

Hi,

We have 5 LPARs on each of our servers. Recently we faced an issue where the LAN adaptor of iseries system failed and we had a five hour outage.
I was considering if we could have IP redundency - so that each LPAR would have 2 IPs pointing one IP which the user access. So if one IP fails, there is a fail-over to the other IP. Could some please guide how this is done in AS/400 system?

Thanks and Regards,
Vik.
