Oracle Solaris Cluster software uses the NTP to maintain time synchronization between cluster nodes. Adjustments in the global cluster occur automatically as needed when nodes synchronize their time. For more information, see the Oracle Solaris Cluster Concepts Guide and the Network Time Protocol's User's Guide at http://download.oracle.com/docs/cd/E19065-01/servers.10k/.
Caution - When using NTP, do not attempt to adjust the cluster time while the cluster is up and running. Do not adjust the time by using the date, rdate, or svcadm commands interactively or within the cron scripts. For more information, see the date (1) , rdate (1M) , svcadm (1M) , or cron (1M) man pages. The ntpd(1M) man page is delivered in the service/network/ntp Oracle Solaris 11 package.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
phys-schost# cluster shutdown -g0 -y -i 0
On SPARC based systems, run the following command.
ok boot -x
On x86 based systems, run the following commands.
# shutdown -g -y -i0 Press any key to continue
The GRUB menu appears.
For more information about GRUB based booting, see Booting a System in Booting and Shutting Down Oracle Solaris 11.2 Systems .
The GRUB boot parameters screen appears.
[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ESC at any time exits. ] grub edit> kernel$ /platform/i86pc/kernel/$ISADIR/unix _B $ZFS-BOOTFS -x
The screen displays the edited command.
phys-schost# date HHMM.SS
phys-schost# rdate hostname
On each node, run the date command.
