System reference codes (SRCs)

System reference codes indicate a server hardware or software problem that can originate in hardware, in firmware, or in the operating system.

A blade server component generates an error code when it detects a problem. An SRC identifies the component that generated the error code and describes the error. Use the SRC information to identify a list of possibly failing items and to find information about any additional isolation procedures.

The following table shows the syntax of a nine-word B700xxxx SRC as it might be displayed in the event log of the management module.

The first word of the SRC in this example is the message identifier, B7001111. This example numbers each word after the first word to show relative word positions. The seventh word is the direct select address, which is 77777777 in the example.

Index Sev Source Date/Time Text
1 E Blade_05 01/21/2008, 17:15:14 (PS700-BC1BLD5E) SYS F/W: Error. Replace UNKNOWN (5008FECF B7001111 22222222 33333333 44444444 55555555 66666666 77777777 88888888 99999999)

Depending on your operating system and the utilities you have installed, error messages might also be stored in an operating system log. See the documentation that comes with the operating system for more information.

The management module can display the most recent 32 SRCs and time stamps. Manually refresh the list to update it.

Select Blade Service Data > blade_name in the management module to see a list of the 32 most recent SRCs.

SRC formats

SRCs are strings of either six or eight alphanumeric characters. The first two characters designate the reference code type.

The first character indicates the type of error. In a few cases, the first two characters indicate the type of error:
  • 1xxxxxxx - System power control network (SPCN) error
  • 6xxxxxxx - Virtual optical device error
  • A1xxxxxx - Attention required (Service processor)
  • AAxxxxxx - Attention required (Partition firmware)
  • B1xxxxxx - Service processor error, such as a boot problem
  • B6xxxxxx - Licensed Internal Code or hardware event error
  • B9xxxxxx - Software installation error or IBM® i IPL error. See "Recovering from IPL or system failures" in the IBM i Information Center at http://publib.boulder.ibm.com/infocenter/systems/scope/hw/index.jsp?topic=/ipha5_p5/iplprocedure.htm.
  • BAxxxxxx - Partition firmware error
  • Cxxxxxxx - Checkpoint (must hang to indicate an error)
  • Dxxxxxxx - Dump checkpoint (must hang to indicate an error)

To find a description of an SRC that is not listed in this PS703 or PS704 blade server documentation, refer to the POWER7® Reference Code Lookup page at http://publib.boulder.ibm.com/infocenter/systems/scope/hw/index.jsp?topic=/ipha8/codefinder.htm.
