Pinned topic how to specify alternate HMC interface during installios

‏2009-09-17T01:32:32Z |
I am trying to restore a VIO server through HMC. The nim_resources.tar is nfs exported from a file server.

The HMC has 2 interface configured

ent0 - Privare network
ent1 - Public network

Both networks are isolated from each other with different switch.

Now the problem:

When running the installios command from HMC and after providing the required parameter, the HMC assumes server IP as the one in private network and going forward ping fails during the lpar bootup
[code}
  1. Connecting to stvus056t-vio
  2. Connected
  3. Checking for power off.
  4. Power off complete.
  5. Power on stvus056t-vio to Open Firmware.
  6. Power on complete.
  7. Client IP address is 10.242.231.69.
  8. Server IP address is 172.17.0.2.
  9. Gateway IP address is 10.242.231.126.
  10. Subnetmask IP address is 255.255.255.192.
  11. Getting adapter location codes.
  12. /pci@800000020000203/ethernet@1 ping unsuccessful {code}

Is there any way I can tell the HMC to use the HMC interface in public network as Server IP and not the private interface ?

Thanks in advance

    hi,
    the manual tells us:
    INSTALLIOS_PRIVATE_IF environment variable must be used.

    But I don't use it, if HMC IP and VIOS IP belong to the same subnet, then use HMC IP as your gatway IP. (-g hmcipaddress)

        Thanks for this, it just saved me a lot of pain trying to get a VIO backup to load. (The HMC was trying to use its private address, and using 'export INSTALLIOS_PRIVATE_IF=eth1' to try to change to the public interface just caused errors when running the installios command)

          This post helps me a lot,

          My HMC and Virtual I/O Server were in the same vlan/subnet, when specifying the gateway ip address, Virtual I/O server installation hang with a 608 error code. Using the HMC ip address as gateway address saved my day ;)

          Thanks a lot for this useful trick.

          Benoît.
