Re-establish a duplicate DR site

After a secondary (backup) site is recovered as the primary (production) site, establish a new secondary DR site.

Prerequisites

The recovery site is up and running as the new production site.

The process of returning activity to a primary (active) production site, plus secondary (backup) site depends on the state of the original primary site.

Procedure

  • If the old production environment becomes available again, complete the following to switch back to the original DR primary site.
    1. Restore/replicate the DR database and file system to the original production database and file system respectively.
    2. Bring up the new DR primary (production) IQ Bot.
    3. Verify new DR primary (production) environment is working, as expected.
    4. Stop the DR IQ Bot services on the DR recovery site.
    5. Establish the replication between the new DR primary (production) and DR secondary (standby) IQ Bot (DB and NAS).
  • If the old DR primary production environment is rendered completely unusable due to the disaster, re-establish a new secondary (standby) DR site. Complete the recovery DR steps to re-establish primary and secondary DR sites.
    1. Restore/replicate the database and file system data from DR environment to the new production environment.

Next steps

No additional steps are required. The DR primary and secondary sites are restored.

  • The bot Activation utility does not need to be run again. Activation occurs when IQ Bot is first deployed to the DR cluster sites only.
  • For any subsequent disasters, only the database query needs to be run on DR secondary (standby) IQ Bot database. This is required because the replication between DR primary (production) and DR secondary (standby) overwrites DR secondary site Bot Runner data in DR secondary site database with DR primary (production) Bot Runner data.
  • Similarly, the mapping between DR primary and DR secondary Bot Runner is established. Use the same mapping for all subsequent disasters or mock drills.
