5.2 Checking Error Information in Messages
When you want to configure the system so that HDLM messages are output to syslog,
specify
user for the name of the system function defined in the /etc/syslog.conf
file. In the following example, the system function name is
user, and messages at the
Information level or higher are output to the
/etc/syslog.conf file:
user.info /tmp/syslog.user.log
You can check path errors by referring to the KAPL08xxx messages that are output to
the syslog.
To obtain detailed information about a path failure, check the execution results of the
view operation as indicated by the error message.
For details on the
view operation, see 6.7 view (Displays Information).
The following is an example of a message:
KAPL08022-E Error in path occurred. ErrorCode =
aa...aa,PathID
=
bb...bb,PathName = cc...cc.dd...dd.ee...ee.ff...ff,DNum =
gg...gg,HDevName = hh...hh
The message elements are explained below:
ErrorCode
The error number generated when Solaris detects a path error.
PathID
The ID assigned to a path. This ID is called the AutoPATH_ID. AutoPATH_IDs
are re-assigned every time the host is restarted. When you want to add a new LU
without restarting the host, AutoPATH_IDs will be re-assigned to each path of the
LU when you execute the
dlmcfgmgr utility for managing the HDLM
configuration.
The path ID is also the same as the
PathID displayed by the dlnkmgr command's
view operation. For details on the view operation, see 6.7 view (Displays
Information).
PathName
The path name indicates a physical path. When you modify the system
configuration or replace a piece of hardware, you should check the path names to
identify the physical paths that will be affected by the change.
A path name consists of the following four elements, separated by periods:
