Live Kernel Update and PowerVC
Abstract
Live Kernel Update of a PowerVC managed LPAR may incorrectly remove a disk from the LPAR
Description
When certain errors are encountered communicating with PowerVC during Live Kernel Update (LKU), the wrong disk may be removed at the end of the LKU processing. This may result in a rootvg or data vg disk being detached and deleted from the LPAR. This can only occur when doing LKU of a PowerVC-managed LPAR, not when doing LKU of an HMC-managed LPAR.
Recommended Action
IBM recommends the following fix be applied before doing any Live Kernel Update of a PowerVC mangaged LPAR. No reboot is required after applying the ifix below:

This table describes which active levels are affected and where to obtain fixes.
Before the APAR fix is available, an interim fix (iFix) is available for each affected level.
The available interim fixes might apply only to the latest Service Packs. If a custom interim fix is required, contact IBM Support.
The interim fixes can be downloaded from the same location by using HTTPS or FTPS.
