Information collected by using the DLMgetras utility for
collecting HDLM error information
Immediately after an error occurs, execute the DLMgetras utility to collect
HDLM error information, because restarting the machine may delete existing
error information already collected by the DLMgetras utility. For details on the
DLMgetras utility and the error information it collects, see
The DLMgetras
Utility for Collecting HDLM Error Information on page 7-3 .
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 or etc/rsyslog.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 view (Displays Information) on page
6-32 .
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 view
(Displays Information) on page 6-32 .
PathName
