3.6 scfdate(1M)

NAME

scfdate - Checks the SCF high-resolution clock and synchronizes with the system standard clock

SYNOPSIS

/opt/FJSVhwr/sbin/scfdate [sync]

AVAILABILITY

FJSVscu, FJSVscu3

DESCRIPTION

scfdate checks the SCF high-resolution clock and then reads the time of the system standard clock in order to reset the SCF high-resolution clock.

The following models can use this command.

• GP7000F model 200/200R/400/400A/400R/600/600R
• PRIMEPOWER 200/400/600/650/850

Running this command without any arguments displays the current time of the SCF high-resolution clock.
Specifying the sync option sets system time from the system standard clock to the SCF high-resolution clock.

Even if this command is offered to PRIMEPOWER 900/1500/2500/HPC2500, and specifies the sync option, operation is invalid.

EXAMPLES

prompt% scfdate
Tue Oct 27 18:40:38 JST 1998
# date 1157
Tue Oct 27 11:57:00 JST 1998
# scfdate sync
Tue Oct 27 11:57:00 JST 1998

NOTES

If you use scftool(1M) or scfconf(1M) to operate the system with the setting for using the SCF high-resolution clock and you change system time with commands such as date(1), you must synchronize the time of the SCF high-resolution clock. Note that only the super user can execute the sync option of this command.
When the system is started in the single user mode, and system clock is changed, after /opt directory is mounted by using maount(1M) and mountall(1M) this command can be executed.

EXIT STATUS

This command returns the following values:

0

Ended normally
