Set Up the /kernel/drv/sd.conf File
When using an sd driver, depending on the HBA driver, you need to edit the /
kernel/drv/sd.conf file to recognize the disks. For details on how to edit
this file, refer to the HBA documentation.
When using an ssd driver, you will not need to edit this file, since the
connected disks will be automatically recognized.
After editing the /kernel/drv/sd.conf file, restart the host by executing
either of the following commands with the reconfiguration option (-r)
specified:
• # reboot -- -r
• boot -r (at the ok prompt)
After restarting the host, use the format command to confirm that the sd or
ssd device that is to be managed by HDLM is displayed.
# format
For details on the settings, refer to the documentation for the HBA or Solaris.
Switch the Kernel Mode
When you install HDLM while the 32-bit kernel mode is being used, only the
32-bit version of HDLM will be installed. When you install HDLM while the 64-
bit kernel mode is being used, both the 32-bit and 64-bit versions of HDLM
will be installed. Before installing HDLM, decide which kernel mode you will
use to operate Solaris, and if needed, change to the desired kernel mode. If
you switch the kernel mode from 32 bits to 64 bits when only the 32-bit
version of HDLM is installed, you must re-install HDLM after the switch is
completed.
To switch the kernel mode currently being used:
1
.
Check the kernel mode currently being used.
Execute the following command:
# isainfo -b
32 will be displayed when a 32-bit kernel is being used, and 64 will be
displayed when a 64-bit kernel is being used.
2
.
Switch the kernel mode.
Execute the following command to switch to either the 32-bit or 64-bit
kernel mode:
¢
To switch to the 32-bit kernel mode:
If Solaris is running, execute the following command:
# reboot -- "boot-device kernel/unix other-boot-options"
To boot at the ok prompt, execute the following command:
boot boot-device kernel/unix other-boot-options
