IBM BigFix Patch is pleased to announce the multibos support for AIX 5.3 TL3 and later versions.
Multibos is an efficient way to apply updates on endpoints that may not have any free alternate disks, but has only one disk available on rootvg. With multibos, users can deploy technology level (TL) or service pack (SP) updates to an endpoint’s standby base operating system (BOS) instance without impacting the active BOS instance. Multibos can help manage downtime and risk during an uprgrade, ensuring continuous operation of the AIX operating system on the endpoint.
Highlights:
The AIX Advanced Deployment Wizard was enhanced to include a section mainly for the following multibos operations:
- Multibos express task: Creating a BOS and deploying TL or SP updates to it
- Creating a standby BOS
- Deploying TL or SP updates
- Updating the boot list
- Removing a standby BOS
- Running preview tasks for installations and updates
This release also includes the release of the “Deploy AIX StartUp/Shutdown script for multibos reboot” Fixlet, which must be deployed before rebooting to a standby BOS.
Actions to Take:
- Ensure that the current rootvg has enough space for each BOS logic volume. The total number of copied logical volumes cannot exceed 128. The total number of copied logical volumes and shared logical volumes are subject to volume group limits.
- Register and configure the AIX Download Plug-in or enable the NFS service and configure an NFS share to deploy TL and SP updates using multibos. For more information, see Registering the AIX download plug-in or Network File System support.
- Ensure that the endpoints contain the expect.base fileset.
- Ensure that you have sufficient amount of disk space on the /var partition to accommodate large files. Use the available tasks to set any size or space limitations. For more information, see Fix pack download configuration.
