fsck
, the operation may not finish. In such a case, perform the operation again
after restoring the path error.
The name of the HDLM device file will not be displayed on the Hardware
Browser of Red Hat Enterprise Linux.
The Linux functionality that adds
LABEL=
to a SCSI device is not supported in
HDLM. Do not use this functionality. With HDLM, access can constantly be
made to the same LU if the name of the HDLM device file is the same.
If all the following conditions are satisfied, even a path in the normal status might
become Offline(E) or Online(E):
•
A storage system that has a SATA drive is being used.
•
There is a heavy I/O load on the storage system.
•
Path health checking is set to ON.
If this problem happens, reduce the I/O load, and then return the path status to
Online by performing an online operation.
Although the following messages are output when you load the alert driver and
the filter driver respectively, HDLM operations are not affected.
sddlmadrv: unsupported module, tainting kernel.
sddlmadrv: module license 'Proprietary: Contact Hitachi for
any bugs' taints kernel.
If you start the host when using an HDLM device as a boot disk, the error message
KAPL05023-E might be output to the syslog file. However, HDLM operations
are not affected.
dlmmgr: KAPL05023-E Could not process the IOCTL(0000125F).
