Applying maintenance to your GPFS system
Before applying maintenance to your GPFS™ system, there are several things you should consider.
Remember that:
- There is limited interoperability between GPFS 4.2 nodes and nodes running GPFS 4.1 This function is intended for short-term use. You will not get the full functions of GPFS 4.2 until all nodes are using GPFS 4.2.
- Interoperability between maintenance levels will be specified on a per-maintenance-level basis. See the IBM Spectrum Scale™ FAQ in IBM® Knowledge Center.
- Maintenance images for GPFS Linux retrieved from the web are named differently from the installation images of the GPFS Linux product. Maintenance images contain the word update in their name, for example: gpfs.base-4.2.2-0.x86_64.update.rpm.
- When applying maintenance, the GPFS file
systems will need to be unmounted and GPFS shut
down on the node being upgraded. Any applications using a GPFS file system should be shut down before
applying maintenance to avoid application errors or possible system
halts. Note: If the AIX® Alternate Disk Install process is used, the new image is placed on a different disk. The running install image is not changed, and GPFS is not shut down. The new image is not used until the node is rebooted.
