man iseltime (8): synchronize BMC SEL time with OS system time

SYNOPSIS

seltime [-sx -NUPRETVF]

DESCRIPTION

seltime is a program that uses IPMI commands to set the BMC SEL time from the OS system time. The OS system time should be in sync with the BIOS Real-Time-Clock. The OS system time may also be kept from drifting via an NTP server. Normally the BIOS will set the BMC time from the RTC during boot, but running this command may be necessary periodically if the system does not reboot for many weeks, for instance. Note that this command should not be run too frequently to avoid BMC timing issues. Once per day should be sufficient.

Run with no options, this command reads the BMC SEL time without setting anything.

This utility can use either the /dev/ipmi0 openipmi driver, the /dev/imb Intel driver, the /dev/ipmikcs valinux driver, a driverless interface, or IPMI LAN.

OPTIONS

-s

Sets the SEL time (no more than once a day).

-x

Causes eXtra debug messages to be displayed.

-N nodename

Nodename of the remote target system. If a nodename is specified, IPMI LAN interface is used. Otherwise the local system management interface is used.

-P/-R password

Remote password for the nodename given. The default is a null password.

-U username

Remote username for the nodename given. The default is a null username.

-E

Use the remote password from Environment variable IPMI_PASSWORD.

-F drv_t

Force the driver type to one of the followng: imb, va, open, gnu, landesk, lan, lan2, lan2i, kcs, smb. Note that lan2i means lan2 with intelplus. The default is to detect any available driver type and use it.

-J

Use the specified LanPlus cipher suite (0 thru 14): 0=none/none/none, 1=sha1/none/none, 2=sha1/sha1/none, 3=sha1/sha1/cbc128, 4=sha1/sha1/xrc4_128, 5=sha1/sha1/xrc4_40, 6=md5/none/none, ... 14=md5/md5/xrc4_40.

-T

Use a specified IPMI LAN Authentication Type: 0=None, 1=MD2, 2=MD5, 4=Straight Password, 5=OEM.

-V

Use a specified IPMI LAN privilege level. 1=Callback level, 2=User level, 3=Operator level, 4=Administrator level (default), 5=OEM level.

-Y

Yes, do prompt the user for the IPMI LAN remote password. Alternatives for the password are -E or -P.
