Review these guidelines before you configure Assure MIMIX for AIX:

  • The file systems protected by Assure MIMIX for AIX should not be automatically mounted at system restart.

  • The file systems protected by Assure MIMIX for AIX should not be mounted or unmounted when a Resource Group is brought online or offline. The mounting and unmounting of the protected filesystems will be performed by Assure MIMIX for AIX.

  • Do not use the Assure MIMIX for AIX Enable Automatic Startup feature, as documented in the User Guide.

  • Assure MIMIX for AIX software must be installed on both PowerHA production nodes and the recovery node.

  • All volume groups associated with an Assure MIMIX for AIX configuration must be enhanced concurrent mode volume groups on both PowerHA production nodes. Use PowerHA C-SPOC to create/change the volume group(s), selecting Fast Disk Takeover or Disk Heart Beat for the Enable Fast Disk Takeover or Concurrent Access option.   

  • Assure MIMIX for AIX file containers and the Assure MIMIX for AIX configuration file systems /usr/scrt/run/c<Primary Context ID> and /usr/scrt/run/c<Failover ContextID> can co-exist on the same enhanced concurrent mode volume group(s) that are part of the Assure MIMIX for AIX configuration. The file systems need to be at least 128MB in size and must have a separate jfslog, jfs2log, or jfs2 inline log since they will not be part of the protected file systems.

By default the Assure MIMIX for AIX File Containers are created on a volume group (Default VG, selected when using the Replication Group wizard), unless otherwise specified.

  • Assure MIMIX for AIX must be configured with a Service IP address (an alias address that follows the application when it is moved between nodes) so that the recovery server can connect to either production server. To configure a Service IP Address, change the production servers Initial host adapter IP Address to the Service IP address used by your application. If your application did not use a Service IP address, create one. The /etc/hosts file on all nodes must contain the Service IP Address and associated IP label.

  • Before starting Assure MIMIX for AIX on the production server, you must stop your application and unmount the protected file systems.
