Common reference codes for software installation

The following table lists the most common reference codes related to a software installation.

If you are looking at reference codes on a system with logical partitions, the reference code gives an indication of the type of partition to which it pertains. For example, the reference code B1xx xxxx indicates a primary partition. The reference code B2xx xxxx indicates a secondary partition.

Table 1. Common reference codes
Symptom	Action
A1xx 19xx A12x 19xx (x is any character)	These reference codes appear if the installation device for an alternate IPL is not ready. Check the following: Is the correct media volume loaded? Is the device ready? Is the device being used for a different purpose than the device was used for during the previous IPL? Is the installation media loaded in the alternate IPL or alternate installation device allocated for that partition? Any of these situations can cause these reference codes to appear. In the first two examples, ensure that the media volume is loaded correctly and that the device is ready. In the last example, you need to wait while the system finds the new installation device. Then perform the appropriate procedure under Installation recovery after using reference codes.
A600 1103	This reference code appears when Licensed Internal Code is damaged. Use the control panel or virtual control panel (Work with Partition Status display) to set the IPL type to D and to set the mode to Manual. Then use the instructions for Upgrading or replacing software using manual installation.
A600 1104	This reference code appears if the installation media is not readable. Either the media is dirty or damaged, or there is an error with the optical device. Clean the media or acquire a new set of media. Then perform the appropriate procedure under Installation recovery after using reference codes.
B101 4500	This reference code appears when an error is detected with the Integrated xSeries^® Server for iSeries™. Make sure that you vary off the Integrated xSeries Server for iSeries before you perform the function that resulted in this reference code. If the reference code still occurs, try the installation again. If the same error occurs again, contact your authorized service provider. Note: Integrated xSeries Server for iSeries is the new name for Integrated PC Server (IPCS) or File Server Input/Output Processor (FSIOP).
B1xx 4504 B1xx 1933	This reference code appears when the system cannot locate the device used for the alternate IPL. Check that the installation media is loaded in correct device and, if necessary, make the device ready. Then perform the appropriate procedure under Installation recovery after using reference codes.
B1xx 4505	These reference codes appear if the installation media is dirty or if the wrong media was loaded. Verify that the correct media is loaded. If the problem still remains, clean the optical disk. If you are using tape, clean the tape head and tape path. Then perform the appropriate procedure under Installation recovery after using reference codes.
B1xx 4507	These reference codes appear if the tape device for the alternate IPL was not found or was not ready. Make sure the tape device is powered on and the correct tape is loaded and ready. To make tape devices ready, you might need to open and close the tape device door. Then perform the appropriate procedure under Installation recovery after using reference codes.
B2pp 1310 (pp is the partition ID)	No alternate IPL device IOP was selected. The IPL will attempt to continue, but there might not be enough information to find the correct alternate IPL load source. Configure an alternate IPL device IOP for the logical partition. Then, retry the partition IPL. If it continues to fail, contact your service provider. For iSeries 8xx and earlier models, refer to Manage logical partitions for more information. For IBM^® System i5, System p5, and IBM eServer™ i5 and p5 systems, see Managing i5/OS™ logical partitions .
B2pp 1320 (pp is the partition ID)	No default load source IOP was selected for a type A or type B IPL. The IPL will attempt to continue, but there might not be enough information to find the correct load source. Configure a load source IOP for the logical partition. Then retry the partition IPL. If it continues to fail, contact your service provider. For more information on iSeries 8xx and earlier models, refer to Manage logical partitions . For information on IBM System i5, System p5, and IBM eServer i5 and p5 systems, see Managing i5/OS logical partitions .
B2pp 3110 (pp is the partition ID)	The power-on operation for the logical partition failed. Scan the reference code history list of the logical partition for previous B2ppxxxx failure reference codes. Resolve each problem found, and then retry the partition IPL. If it continues to fail, contact your service provider.
B2pp 3200 (pp is the partition ID)	The logical partition failed to initialize a program load. If you performed a power-on operation from IPL type D, remove the installation media (optical or tape media), clean the device and clean the media if possible. Insert the media again and attempt to power on using IPL type D. Verify that the device is addressed correctly. Verify that the media is in the correct device. Verify that the media in the device is compatible. Verify that the IOP selected as the IPL resource is correct. Retry the partition IPL.
B2xx xxxx	All other reference codes: If you performed a D-mode IPL, clean the device and media, and then retry the same type of power-on operation. For more information, refer to the following topics: For iSeries 8xx and earlier models, see Logical partitions . For IBM System i5, System p5, and IBM eServer i5 and p5 systems, see Partitioning for i5/OS .
B608 1105	This reference code occurs when you exit from the automatic installation because an alternate installation device that is attached to the system has one of the following problems: The device is enabled, but it is not ready because the tape is not loaded. The device is not enabled as an alternate installation device. The device itself has a problem. To use the alternate installation device, do the following: Power off the system. If necessary, fix the device. Power on the system. Verify that the alternate installation device is enabled as an alternate installation device. Load the tape media in the alternate installation device and start the installation procedure again.
B900 3121	This reference code occurs when an IPL is attempted after an installation failure. You need to reinstall some or all of the operating system. Start with the media volume containing the base operating system. (For optical media, this volume is labeled B29xx_01.) Then perform the appropriate procedure under Installation recovery after using reference codes.
2644 3136	This reference code appears if the tape device is assigned to another system or partition. Go to the other system or partition and vary off this tape device. Make sure the correct tape is loaded. Then perform the appropriate procedure under Installation recovery after using reference codes.
Any other reference code	Go to Troubleshooting software installation problems, and follow the instructions there.
