IXOS HDSK Migration 

By - Linux No Comments

MNX Solutions works on many UNIX based systems, one of which is IXOS (now called OpenText).

We needed to migrate from WORM (9.1GB) media to a hard disk based configuration for performance, scalability and disaster recovery purposes. Below is the high level procedure I used during the migration to migrate from WORM to HDSK, on IXOS EconServer 5.5C..

  • Create temporary logical archive XX
  • Create temporary Disk pool, HDSK_<Logical Arch> under /ixos/migration/migr/<Logical Arch>
  • Create log directory /ixos/migration/migr/<Logical Arch>_log
  • Run buffer purge
  • Write WORM
    • Migrate pool using utilities pool migration
      • From <Logical_Arch>_<POOL> i.e. T3_T3_WORM
      • To <Logical_arch>_<POOL> i.e. XX_HDSK_T3

  • If errors,..
    • Partition check Against database
      • Run again with recovery method if errors
    • database against partition
      • run again with recovery method if errors
    • Eject original
    • Promote backup to original
      • Partition check Against database
        • Run again with recovery method if errors
      • Database against partition
        • run again with recovery method if errors
  • Detach partition from original pool, remove pool
  • Detach disk partition from XX Logical archive
  • Create new pool [HDSK] for migrated archive, select existing Disk partition that was used during migration.
  • Maybe remove any jobs associated with logical archives, that you wish not run anymore.
  • Create a backup of the new HDSK partition and ensure that regular backups are scheduled and running.
