KAMN725-W (E+L)(Linux(x86))
Execution of the SCSI command on the device aa....aa ended abnormally. (details code: bb....bb, server: cc....cc, host address: dd....dd (0xee....ee))
A SCSI command execution error has occurred for device aa....aa. If bb....bb is OPEN or IOCTL, message KAMN601-W is output before this message.
aa....aa: Name of the device specified in the server environment definition operand in which the error occurred
For details about the device name, see the following table:
Operand name |
Environment |
Device name |
---|---|---|
scsi_device |
Multipath software is HDLM. |
HDLM logical device name |
Virtual environment based on VMware ESXi |
Symbolic link name |
|
Virtualization environment based on KVM |
||
All other cases |
||
dmmp_device |
Multipath software is DMMP. |
DMMP logical device name (/dev/xxx) is output after the DMMP logical device name. xxx is the path for which the failure occurred. |
bb....bb: Detail code
Detail code |
Meaning |
---|---|
OPEN |
An attempt to open device aa....aa failed. The device does not exist. |
IOCTL |
aa....aa does not support SCSI reservations. |
ALREADY-RESERVATION |
aa....aa is already reserved. Another possibility is that it was reserved by a remote system in a hot standby. |
IO-ERR |
An I/O error has occurred on aa....aa. |
cc....cc: Server alias name of the server that is using a shared disk on aa....aa.
dd....dd: The following are displayed, listed by detail code.

ALREADY-RESERVATION |
Host address of the system that has reserved the disk |
IO-ERR |
Local system host address (Note: When this message is output by the monscsiclr command, this value is always 99999999.) |

ALREADY-RESERVATION |
Displays, in hexadecimal, the content displayed in dd....dd. This is the specification key of the sg_persist command that is executed during corrective actions. |
IO-ERR |
- S:
-
Resumes processing.
- O:
-
Contact a system administrator.
- Action:
-
Take one of the following actions, as indicated by the detail code:
Detail code
Corrective action
OPEN
Specify a symbolic link or HDLM logical device name for the scsi_device operand. Alternatively, specify the logical device of the multipath software (DMMP) in the dmmp_device operand.
IOCTL
Specify a symbolic link of a shared disk supporting SCSI Reserve or an HDLM logical device name for the scsi_device operand. Alternatively, specify the logical device of the multipath software (DMMP) in the dmmp_device operand.
ALREADY-RESERVATION
If the active server is started after any of the operations or events listed below, this detail code is output and the processing to start the active server fails. In such a case, either execute the reservation release command (monscsiclr command) or release the reservation by following the procedure described in the section on handling a server that does not release a reservation in the manual HA Monitor Cluster Software (for Linux(R) (x86) systems), and then restart the active server.
-
When the active server was stopped, the reservation could not be released, for example, because of an I/O error (the KAMN726-E message is displayed).
-
A host failure occurred on the active system while hot standby processing was not possible (for example, because the standby server was inactive).
-
The OS was shut down while the active server was running.
-
When hot standby processing was performed as a result of a host failure, the active server terminated before the failed host and the standby server were started.
If none of the above applies, see the sections on handling device failures on a shared disk in the manual HA Monitor Cluster Software (for Linux(R) (x86) systems), and take the corrective action described there.
IO-ERR
See the section on handling shared disk device failures in the manual HA Monitor Cluster Software (for Linux(R) (x86) systems), and take the corrective action described there.
If you are using a KVM-based virtualization environment, make sure that the settings are specified correctly by referring to the description of the KVM settings in the manual For Linux(R) (x86) Systems HA Monitor Cluster Software.
