Setting up shared disk clusters and IO fencing for AIX

On AIX platforms, make sure that:

• The users who start Adaptive Server have permission to access the SCSI fixed disks (/dev/rhdisk#), since Adaptive Server can use the databases or the quorom.

• All nodes are running AIX

• All disks:

  • Are PR-capable (DS3000, DS4000, or newer).

  • Are hdisks.

  • Permit read/write access, using the following “chmod” commands on both the hdisk and the corresponding character access device rhdisk:

    • chmod 666 hdisk#
      

    • chmod 666 rhdisk#
      

The user or process must have permissions to manage the raw devices, using PV_ROOT, PV_SU_, or PV_KER_RAS privileges.
