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
