Veritas File System requirements

Veritas File System requires that the values of the Solaris variables lwp_default_stksize and svc_default_stksize are at least 0x6000. When you install the Veritas File System package, VRTSvxfs, the VRTSvxfs packaging scripts check the values of these variables in the kernel. If the values are less than the required values, VRTSvxfs increases the values and modifies the /etc/system file with the required values. If the VRTSvxfs scripts increase the values, the installation proceeds as usual except that you must reboot and restart the installation program. A message displays if a reboot is required.

To avoid an unexpected need for a reboot, verify the values of the variables before installing Veritas File System. Use the following commands to check the values of the variables:

# echo "lwp_default_stksize/X" | mdb -k 
lwp_default_stksize:
lwp_default_stksize:            6000

# echo "svc_default_stksize/X" | mdb -k 
svc_default_stksize:
svc_default_stksize:            6000

If the values shown are less than 6000, you can expect a reboot after installation.

Note:

The default value of the svc_default_stksize variable is 0 (zero), which indicates that the value is set to the value of the lwp_default_stksize variable. In this case, no reboot is required, unless the value of the lwp_default_stksize variable is too small.

To avoid a reboot after installation, you can modify the /etc/system file with the appropriate values. Reboot the system prior to installing the packages. Add the following lines to the /etc/system file:

set lwp_default_stksize=0x6000
set rpcmod:svc_default_stksize=0x6000
