Ringnode Mirroring

One Ringnode, the Primary Ringnode, inserts into the ring and is monitored by the server. If the Primary Ringnode fails, the server shuts it down safely and initializes the second, or Hot Standby Ringnode, giving it the same LAA (locally administered node address) as the Primary Ringnode.

To perform Ringnode Mirrroring:

1. Load MADGEODI onto one Ringnode. Specify an LAA on the command line, by using the NODE command (see Figure 1).

2. Load MMIRROR.NLM. Specify a BOARD number to identify which adapter is the Primary Ringnode. Specify a MIRRORPORT (for EISA and AT Plus Ringnodes) or MIRRORSLOT (Micro Channel Ringnodes) to identify which adapter is the Hot Standby Ringnode (see Figure 1).

   LOAD MADGEODI PORT=3000 NODE=400012131415

   LOAD MMIRROR BOARD=1 MIRRORPORT=4000

   LOAD ROUTE BOARD=1

   BIND IPX TO MADGEODI NET=2

3. Bind the driver.
