Determining storage space required for a software upgrade
Before you schedule a time to install the IBM® i release, determine the available storage space and the storage space that is required.
Load-source disk unit requirements
- IBM i 7.3 load-source disk size needs to
be at least 35-70 GB depending on the type of disk being used.
- Minimum of 35 GB for 520-byte sectors (DS8000, virtual disks with VIOS as server)
- Minimum of 40 GB for 512-byte sectors (SVC, Storwize, virtual disks with VIOS, VSCSI, or IBM i as server)
- Minimum of 70 GB for Native-attached SAS/SCSI (520-byte or 4K sectors)
- To upgrade to IBM i 7.3, you must allocate additional space for Licensed Internal Code. See Required (If upgrading from IBM i 7.1): Allocating additional space for Licensed Internal Code for steps to allocate the additional space.
The procedures in this topic might not include all requirements for storage that you have on your system. If you are preparing to upgrade or replace software using an image catalog, ensure that you reveiw the topic, Determining storage requirements for image catalog installation.
To determine if you have enough storage space for the new release, perform the following steps:
Repeat this process whenever you make any changes to your system that affect the available disk storage space.
