device is executed. For example, when this utility executes an operation specified
with the
-o
parameter for
/dev/sddlmaa
,
/dev/sddlmab
, and
/dev/
sddlmac
, the confirmation message KAPL10339-I is not displayed for the
processing of each device. This message is displayed once at the beginning of the
operation. If you enter
y
, the processing for all the specified HDLM devices (
/
dev/sddlmaa
,
/dev/sddlmab
, and
/dev/sddlmac
) is executed continuously.
„ After changing partition configuration directly from a SCSI device for LUs
corresponding to the HDLM devices not to be managed, if the HDLM device is
returned to management target, execute the following operations:
1.
Execute the dlmcfgmgr
utility
with the -i parameter
specified.
2.
Execute the dlmcfgmgr
utility
with -r parameter specified.
„ If you execute the
dlmcfgmgr
utility with the
-i
parameter specified, the HDLM
device that is not a management target can be changed to a managed status. At this
time, if an error occurs anywhere on the paths to an HDLM device and you change
that HDLM device to a managed status, the message KAPL08026-E might be
output to the syslog. However, HDLM operations are not affected.
„ If you execute the
dlmcfgmgr
utility with the
-r
parameter specified, the I/O and
I/O error counts for existing paths displayed when the HDLM command
(
dlnkmgr view -path
) is executed are initialized to 0.
„ If you execute the
dlmcfgmgr
utility with the
-r
parameter specified while one
or more HDLM devices are mounted, an error message (KAPL05023-E) is output
to the syslog. However, HDLM operations are not affected.
„ If an HDLM device that is managed on the active host is changed to be managed
on the standby node, and then the same HDLM device is excluded from
management on the standby node then, during the cluster creation, an error will
occur when the active node is failed over. When the
dlmcfgmgr
utility is
executed with the
-o
parameter specified to exclude an HDLM device from
management on the standby node, make sure that you exclude the same HDLM
device from management on the active node.
„ When an HDLM device is bound to a raw device, do not attempt to exclude that
HDLM device from management by executing the
dlmcfgmgr
utility with the
-o
parameter specified. If the HDLM device is not being managed, an error will
occur when the raw device is accessed.
„ After configuring an HDLM device by executing the
dlmcfgmgr
utility, do not
change the settings of the
sysfs
interface that handles SCSI devices.
„ After configuring an HDLM device by executing the
dlmcfgmgr
utility, if you
unload the HBA driver, perform the following operations. If you load the HBA
driver without first performing the operations, the number of HDLM paths that
