Service Pack VIOS SP-02 limitations

The reject option of the updateios command is not supported on VIOS SP-01 and later.

VIOS Shared Storage Pool requirements and limitations

The following requirements and limitations apply to enhancements to virtual storage, including shared storage pools and thin provisioning. These requirements and limitations do not apply to VIOS classic function.

Requirements for Shared Storage Pools

Limitations for Shared Storage Pools

NOTE: The system reserves a small amount of the reported Shared Storage Pool capacity to record consistency records. The remainder of the Shared Storage Pool capacity is available for storage of virtual client partition user data. Shared Storage Pool threshold monitoring should be used to notify the VIOS Administrator when free capacity falls below an acceptable level. The default threshold monitoring is set to alert when the free capacity in the pool is lower than 75% of the total capacity. As a precautionary measure, the VIOS Administrator should not allow the free capacity to drop below 5% of the total capacity or I/O operations on the virtual client partition may fail. In the event that no storage capacity is available, physical volumes must to be added to the pool or data deleted from the pool to create additional free capacity.

Installation information

To install a Service Pack, log in to VIOS as padmin , and then follow these steps, entering the specified commands.

If interim fixes are installed on your VIOS, the updateios command prompts you to choose whether or not to remove the interim fixes before it installs the Service Pack. The prompt is a Yes/No (y/n) prompt.

To complete the fix pack update, you must remove the interim fixes before running the updateios command again, or by answering "Yes" ( y ) when the updateios prompts you to let it remove interim fixes.

After the interim fixes have been removed, repeat steps two and three of the installation instructions.
