Dell ObjectScale 1.3 Administration Guide

Set Static IP using API for iDRAC

This topic describes how to update static IP using API for iDRAC after the deployment of ObjectScale Appliance.

1. Set external static IP when iDRAC is connected to an external management network and set internal static IP when iDRAC is connected to ObjectScale backend network.
   • To set external static IP when iDRAC is connected to an external management network, use the following command to patch:kubectl -n gc patch server <node_name> --type merge --patch-file static_ip_patch.yaml. Below is a sample payload for setting externally accessible static iDRAC IP:

     provo-enterprise:~/payload # cat static_ip_patch.yaml
     spec:
       bmc:
       - nicSettings:
         - ipV4Add:
           - address: "10.236.71.25"
             gateway: "10.236.71.1"
             subnetMask: "255.255.255.0"
           DNSFromDHCP: "Disabled"
           DHCPEnable: "Disabled"
       reInitialize: true
     provo-enterprise:~/payload # kubectl -n gc patch server murray-enterprise --type merge --patch-file static_ip_patch.yaml
     server.mw.dell.com/murray-enterprise patched
     provo-enterprise:~/payload #

   • To set internal static IP when iDRAC is connected to ObjectScale backend network, use the following command to patch:kubectl -n gc patch server <node_name> --type merge --patch-file static_internal_ip_patch.yaml

     To determine the internal iDRAC IP to be set, you can check the private IP of the node using ip addr command and derive the iDRAC IP using the private IP as follows.

     NOTE:The Private interface IP is always 169.254.<rack_id>.<100+nodeid> and it gets automatically assigned.
     If the IP assigned to the private interface is 169.254.3.108, then the iDRAC IP would be 169.254.3.158 (hint: the last octet of iDRAC IP is 50+last octet of the private IP).
     You can also determine the internal iDRAC IP to be set by executing the below script idrac.sh in /var/atlantic/files of each node:

     admin@provo-cactusjack:~> cd /var/atlantic/files/ admin@provo-cactusjack:/var/atlantic/files> sudo sh idrac.sh
     169.254.6.151/17 
     admin@provo-cactusjack:/var/atlantic/files>

     Gateway to be provided in the payload is always 169.254.0.1and the subnet mask to be provided is always 255.255.128.0.

     Below is a sample payload for setting internal iDRAC IP:

     provo-enterprise:~/payload # cat static_internal_ip_patch.yaml
     spec:
       bmc:
       - nicSettings:
         - ipV4Add:
           - address: "169.254.2.152"
             gateway: "169.254.0.1"
             subnetMask: "255.255.128.0"
           DNSFromDHCP: "Disabled"
           DHCPEnable: "Disabled"
       reInitialize: true
     provo-enterprise:~/payload # kubectl -n gc patch server murray-enterprise --type merge --patch-file static_internal_ip_patch.yaml
     server.mw.dell.com/murray-enterprise patched
     provo-enterprise:~/payload #

2. Wait till the server status is Ready.

   provo-enterprise:~/payload # kubectl get servers -A
   NAMESPACE   NAME                POWER STATUS   PROVISIONING STATUS   COMMAND EXECUTING     BMCENDPOINT   SUBSCRIPTION_RECONCILE_STATUS

   gc          murray-enterprise   On             Busy                  CollectingInventory                 NotRun
   gc          ogden-enterprise    On             Ready                                                     NotRun
   gc          orem-enterprise     On             Ready                                                     NotRun
   gc          sandy-enterprise    On             Ready                                                     NotRun
   provo-enterprise:~/payload #
   provo-enterprise:~/payload #  kubectl get servers -A
   NAMESPACE   NAME                POWER STATUS   PROVISIONING STATUS   COMMAND EXECUTING   BMCENDPOINT   SUBSCRIPTION_RECONCILE_STATUS
   gc          layton-enterprise   On             Ready                                                   NotRun
   gc          lehi-enterprise     On             Ready                                                   NotRun
   gc          logan-enterprise    On             Ready                                                   NotRun
   gc          murray-enterprise   On             Ready                                                   NotRun
   gc          ogden-enterprise    On             Ready                                                   NotRun
   gc          orem-enterprise     On             Ready                                                   NotRun

3. Do an inventory refresh using the following command:
   NOTE:This is a mandatory step after setting any static IP for iDRAC.

   kubectl patch server orem-enterprise --type='json' -p='[{"op": "add", "path": "/spec/reInitialize", "value":true}]' -n gc

4. Wait till the server status is Ready.

   gc          orem-enterprise     On             Ready                                                   NotRun
   gc          sandy-enterprise    On             Ready                                                   NotRun

5. Verify that IP is set via ipmitool.
   For this, SSH to the node whose iDRAC IP needs to be verified, and execute the following command:

   admin@murray-enterprise:~> sudo ipmitool lan print

   Auth Type Support       : MD5
