Service request numbers (SRNs)
Service request numbers (SRNs) are error codes that the operating system generates. The codes have
three digits, a hyphen, and three or four digits after the hyphen. SRNs can be viewed using the AIX
diagnostics or the Linux service aid “diagela” if it is installed.
Note: The “diagela” service aid is part of the Linux service aids for hardware diagnostics. The service
aids are separate from the operating system and are available for download from the Service and
productivity tools for Linux on POWER systems site.
Using the SRN tables
The service request number (SRN) list is in numerical sequence. The failing function codes (FFCs) are
provided to aid in locating a failing component.
1. Look up a service request number when you see an error code with a hyphen.
The SRN is in the first column of the SRN table in numerical order.
The SRN might have an associated FFC number. Possible FFC values for SRNs are displayed in the
second column of the table. FFC numbers might be the first three digits of the SRN or the last three
digits, or might not be in the SRC.
The third column describes the problem and an action to take to try to fix the problem. The
description also includes how to find the FFC number for an SRC if one exists.
2. See “Failing function codes 151 through 2E33” on page 181 for a description of each FFC value.
3. If the SRN does not appear in the table, see “Solving undetermined problems” on page 227.
4. After replacing a component, verify the replacement part and perform a log-repair action using the
AIX diagnostics.
101-711 through FFC-725 SRNs
AIX might generate service request numbers (SRNs) from 101-711 to FFC-725.
Replace any parts in the order that the codes are listed in Table 25.
Note: An x in the following SRNs represents a digit or character that might have any value.
Table 25. 101-711 through FFC-725 SRNs
SRN FFC Description and Action
101-711 to
101-726
711 to 726 The system hung while trying to configure an unknown resource.
1. Run the stand-alone diagnostics problem determination procedure.
2. If the problem remains, refer to “Failing function codes 151 through 2E33” on
page 181 to find the FFC that matches the last three digits of the SRN.
3. Suspect the device adapter or device itself.
101-888 210 227 The system does not IPL. Go to “Performing the checkout procedure” on page 184 or
undetermined problem procedure.
101-2020 The system hung while trying to configure the InfiniBand Communication Manager.
This problem may be attributed to software. Report this problem to the AIX Support
Center.
101-2021 The system hung while trying to configure the InfiniBand TCP/IP Interface. This
problem may be attributed to software. Report this problem to the AIX Support
Center.
101-xxxx xxxx The system hung while configuring a resource. The last three or four digits after the
dash (-) identify the failing function code for the resource being configured. Go to
undetermined problem procedure.
