IOCTL when installing HDLM because HDLM devices are not SCSI devices.
HDLM rejects the IOCTL request and assumes that the IOCTL processing has
failed. The error message (KAPL05023-E) is output to the syslog, but HDLM
operations are not affected.
This message is also output in the following cases, but HDLM operations are not
affected:
• You execute the utility for collecting HDLM error information
(
DLMgetras
).
• The system is started.
(2) File Systems Supported by HDLM
When using a file system, the related programs are as follows:
• ext2 (supplied with the OS)
• ext3 (supplied with the OS)
• ReiserFS(supplied with the OS)
(3) Boot Disk Environments Supported by HDLM
HDLM supports boot disks in any of the environments listed in
Table 3-37: Operating Environments for Boot Disks When Using SUSE LINUX
