Checking node status

Via CLI

Run nodels all nodelist.status for a list of nodes and their statuses.

omnia-node00001: installing
omnia-node00002: booted
omnia-node00003: powering-on
omnia-node00004: booted

Possible values of node status are powering-off, powering-on, bmcready, installing, booting, post-booting, booted, failed.

Caution

Once xCAT is installed, restart your SSH session to the control plane to ensure that the newly set up environment variables come into effect. This will also allow the above command to work correctly.

Via omniadb

  1. To access the DB, run:

    psql -U postgres

\c omniadb

  2. To view the schema being used in the cluster: \dn

  3. To view the tables in the database: \dt

  4. To view the contents of the nodeinfo table: select * from cluster.nodeinfo;

    id  | serial  |        node        |            hostname            |     admin_mac     |   admin_ip   |    bmc_ip    |    ib_ip     |   status   | bmc_mode |   switch_ip   | switch_name | switch_port

Possible values of node status are powering-off, powering-on, bmcready, installing, booting, post-booting, booted, failed.

Note

  • For nodes listing status as ‘failed’, provisioning logs can be viewed in /var/log/xcat/cluster.log on the target nodes.

  • Information on debugging nodes stuck at ‘powering-on’, ‘bmcready’ or ‘installing’ for longer than expected is available here

  • A blank node status indicates that no attempt to provision has taken place.
