XSCF cheat sheet


The eXtended System Control Facility Unit (XSCFU) is a service processor that operates and administrates both midrange servers. The XSCFU diagnoses and starts the entire server, configures domains, offers dynamic reconfiguration, as well as detects and notifies various failures. The XSCFU enables standard control and monitoring function through network. Using this function enables starts, settings, and operation managements of the server from remote locations.
Connecting a domain

Check for the available domains on the servers :

XSCF> showdomainstatus -a
DID Domain    Status
00            Running
01            Running
02            Running
03              –

Now to connect to the domain with ID 00 :

XSCF> console -d 0

Power/reboot/reset/panic commands

Poweron all domains

XSCF> poweron -a

Poweron only domain 0

XSCF> poweron -d 0

Poweroff all domains

XSCF> poweroff -a

Poweroff domain 0

XSCF> poweroff -d 0

Reboot XSCF

XSCF> rebootxscf

The 3 modes to reset a domain are :

por: To reset the domain
panic: To panic the domain
xir: To reset the CPU in domain

XSCF> reset -d 0 por
XSCF> reset -d 0 panic
XSCF> reset -d 0 xir

Send a break signal to a domain (with ID 0)

XSCF> sendbreak -d 0

User Administration

Creating a New user

XSCF> adduser -u 345 admin

Delete a user

XSCF> deleteuser admin

Disable a user

XSCF> disableuser admin

Enable a user

XSCF> enableuser admin

Display user account information

XSCF> showuser -a

Set or change a User (admin) password

XSCF> password admin

Network related commands

Display complete network configuration

XSCF> shownetwork  -a

Set IP address for XSCF-LAN#0 in the XSCFU#0

XSCF> setnetwork xscf#0-lan#0 -m

We must apply the network settings and reboot the XSCF in order to the network settings to take effect :

XSCF> applynetwork
XSCF> rebootxscf

Setup 2 NTP servers with IP and

XSCF> setntp
Please reset the XSCF by rebootxscf to reflect the ntp settings.

To delete a NTP server

XSCF> setntp -c del
Please reset the XSCF by rebootxscf to reflect the ntp settings.

We can take a snapshot of M series servers XSCF either on a remote server or on a USB device locally connected. To take a snaphot on a remote system (in /var/tmp directory) by using root user credentials :

XSCF> snapshot -L F -t root@

To take the snapshot on a Local USB device connected to the server :

XSCF> snapshot -L F -d usb0

Connect DVD Device to a domain

Run the following from the XSCF to connect the DAT & DVD to the needed port based on the domain(s) configuration.

XSCF> cfgdevice -q -y -c attach -p 0-0

Confirm that the device is attached to domain and is enabled :

XSCF> cfgdevice -l

From the OS prompt configure the newly added DVD device and restart the volmgmt service:

# cfgadm -c configure # c0
# /etc/init.d/volmgt start


Display current hostanems of XSCF units

XSCF> showhostname -a

To set hostname and DNS domain name for XSCF doamin respectively

XSCF> sethostname xscf#0 hostname01
XSCF> sethostname -d
