Troubleshoot the upgrade

Find information about some of the problems that you may run into when upgrading your server.

This topic contains information related to some upgrade-specific problems that may occur. In almost every case, the time you spend planning for the upgrade and performing the upgrade according to instructions can prevent these problems from occurring.

• The IPL takes longer than you expect.

  Check the system reference code (SRC) on the control panel display. For information about the SRC, use the IPL system reference code finder topic. If the SRC indicates that SPCN code is being loaded, the IPL may take up to 45 minutes. Do not try to stop it. If you suspect a problem, contact your service provider.

• Bus numbers change.

  An expansion unit conversion causes changes to the server resources. For information, see the Plan to convert the expansion unit topic.

• The console does not come up when you perform a normal IPL.

  Call your service provider.

For more information, see the preventive service planning (PSP) document. The PSP document for V5R3 upgrades is SF98168. This PSP document describes High-Impact and PERvasive (HIPER) problems.
