3. Creating an HDLM Environment

To boot at the

ok

prompt, execute the following command:

boot

boot-device

kernel/unix

other-boot-options

To switch to the 64-bit kernel mode:

If Solaris is running, execute the following command:

# reboot -- "

boot-device

kernel/sparcv9/unix

other-boot-options

"

To boot at the

ok

prompt, execute the following command:

boot

boot-device

kernel/sparcv9/unix

other-boot-options

(6) Set Up the /etc/system File

HDLM uses a maximum of 8 KB of the stack for the kernel thread. Add the usage of

HDLM to this maximum value, specify that total value as the stack size for the kernel

thread, and then install HDLM. In Solaris 10,

default_stksize

has priority over

lwp_default_stksize

. Therefore, if

default_stksize

is specified in

/etc/

system

, add 8 KB to the value specified in

default_stksize

. If the documentation

for the volume manager or file systems that use HDLM devices specify that the stack

size for the kernel thread is to be expanded, the value mentioned in the documentation

must be also added to the stack size.
The procedure for increasing the stack size of the kernel thread from the default size

in a system with a 64-bit kernel is as follows:
In Solaris 8 or Solaris 9

Add

set

lwp_default_stksize=0x6000

to

/etc/system

, and then restart

the host.

In Solaris 10

Add one of the following parameters to

/etc/system

, and then restart the host:

set lwp_default_stksize=0x8000

set default_stksize=0x8000

The

default_stksize

parameter takes precedence when both parameters are

specified.

(7) Set Up the /etc/syslog.conf File

The

dlmsetconf

utility and the

DLMgetras

utility for collecting HDLM error

information output messages to syslog. See the

/etc/syslog.conf

file (system log

configuration definition file), and then check if it is set so that messages with a level
