KAMN725-W (E+L)

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
	All other cases
dmmp_device	Multipath software is DMMP.	DMMP logical device name (/dev/xxx) is output after the DMMP logical device name, where xxx indicates the name of the path where the error occurred.

bb....bb: Detail code

Detail code	Meaning
OPEN	An attempt to open aa....aa failed. aa....aa 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.

Detail code	Text displayed
OPEN	*
IOCTL
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.)

ee....ee: The following are displayed, listed by detail code.

Detail code	Text displayed
OPEN	*
IOCTL
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.
