3. Creating an HDLM Environment

104

(4) 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.

(5) 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 -- "
