If any path cannot be placed online due to an error, the KAPL01039-W
message will appear. To ignore such paths and to continue processing, type
y. To cancel the processing, type n.
Recheck the statuses of the paths that cannot be placed online, and resolve
the problem.
Actions to Take for a Path Error in a Boot Disk Environment
This section describes the action to take if an error occurs in a boot disk
environment on a path connecting to the boot disk.
Path Errors During Boot Processing
The procedure for investigating the cause of an error, and the appropriate
action to take, will differ according to the stage of the boot processing during
which the path error occurred. The following describes error investigation
methods at each stage of boot processing.
When a Path Error Occurs at the Initial Stage of Boot Processing
The initial stage of boot processing is the period before the root file system's
mount device (one of the paths to the boot disk) specified as the boot device
in the OBP is switched (remounted) to the device specified in the rootdev
parameter. At this stage, accessing the boot disk does not involve the HDLM
driver: The boot disk is accessed via the path specified as the boot device in
the OBP. If an error occurs on this path at this stage, boot processing will be
cancelled. In this case, investigate the error and take appropriate action,
referring to the following information:
•
The message output to the console by the OBP
•
The message output to the console by Solaris
•
The message output to the console by the HBA driver
In Solaris 8 or Solaris 9, if an error occurs only on the path specified as the
boot device in the OBP, you can boot the system by specifying, in the OBP, a
boot device name with a different path. In Solaris 10 or Solaris 11, reboot
after recovering from the path error.
When a Path Error Occurs After the HDLM Driver Starts Path Processing
At completion of the initial stage of boot processing, the HDLM driver starts
accessing the boot disk using multiple paths. If a path error occurs at this
stage, recovery action will depend on whether or not the HDLM manager has
started.
When a path error occurs before the HDLM manager starts
If boot processing is cancelled due to errors on all paths to the boot disk
HDLM does not output the KAPL08022-E message on detection of a path
error. Investigate the error and take appropriate action, referring to the
following information:
