Hitachi Dynamic Link Manager Software Users Guide for Linux

If you are using a kernel that supports Xen on SUSE LINUX Enterprise
Server 10 or SUSE LINUX Enterprise Server 11, change the initrd file
name specified in module to the initial RAM disk image file for the SCSI
device.
When editing the file, be careful of the following:
¢
When an option that depends on the user environment is specified:
Be careful not to delete the option.
¢
When the boot loader is ELILO running on an IPF host, and an option
that depends on the user environment is not specified:
Comment out or delete append.
13. Edit the boot loader configuration file, and specify the settings to be used
during startup.
¢
When GRUB is used as the boot loader:
Change the number specified for default so that the settings copied
in step 9 are used during startup. This number represents the number
of the valid title when counted from 0.
The following shows an example of settings when the first title is
valid:
default=0
¢
When ELILO is used as the boot loader:
Specify the value LABEL in default.
The following is an example of the edited settings.
default 2.6.9-55.EL-sd
14. Edit the /etc/opt/DynamicLinkManager/hdlm.conf file.
Change the hdlm_cfg_all setting to hdlm_cfg_all=n so that HDLM is not
configured when the server starts.
15. If any application directly specifies the HDLM device name, change the
application settings so that the SCSI device is specified. For details on
how to configure settings for each application, see the documentation for
that application.
If you restart the server, HDLM is not configured. Note that, if an
application directly specifies the HDLM device name, an error message
appears when you restart the server.
16. Shut down the host.
Execute the following command to shut down the host:
# shutdown -h now
17. Reduce the number of paths to the LU (system disk) and then change the
configuration from a multi-path configuration to a single-path
configuration.
18. Start the host.
19. After the host starts, check that migration to the SCSI boot disk
environment was successful and that the HDLM boot disk environment is
not used.
