Cray YMP-EL boot up sequence and annotated configuration files

 

Cray EL boot sequence for sn5411

This document shows the boot sequence, as seen from the system console of a 2 IOS, 8 CPU Cray EL followed by the IOS and system configuration files. The later of which is passed to Unicos during the boot.

User input in bold.

HK68/V30 ver 01.04 -Power Up
RTSCOPE 68020 v1.24
After power-up the First board in the first IOS slot, a Hurikon master I/O processor is reset using the button under the front access flap. As this is a powerup from cold rather than a warm reset it performs some self tests.The master IOS scans itsself and looks down its scsi-bus to find the ISO disk and in this case QIC and Exabyte tape drives.
No FPU Present

After the system power ready lights have shown on the front panel load is typed to pull in the IOS from the attached IOS scsi disk. At this pont we are now running in the IOP RAM memory rather than from ROM.

MASTER IOS load complete.
After the IOS copyright message the IOS starts to scan the attached IOS hardware. First it again discovers the IOS disk then looks for other VME boards in the IOS. It finds the Ethernet then Fddi controler followed by 4 disk controlers. This is a well equiped machine.Scanning down the scsi buses attached to the disk controler 8 DD5S ( 5GB Seagate Barracuda) disks are found.

Finally the two IOP connected tape units are found again

At this point the IOS is looking for Vector hardware down the Y1 Bus and find 8 cpus and 4 memory boards. This part of the process is guided by the /IOS file on the IOS disk.

IOS 1 load complete.

The slave IOS 1 is now reset from IOS0 and loads going onto discover its own 8 disks.
Both IOSs are now loaded and ready. IOSs are loaded sequentally and take about 2 minutes each. The Max possible number of IOSs was 16

The boot program runs on the IOS first clearing out memory then loading in the Unicos kernel and system configuration file. The info lines show the kernel opening IOS paths ready for ATM, fddi, and ethernet networking.
Unicos starts to come to life on CPU0. This kernel came from the initial install and was built by sos ( I know him). Further settings are obtained from the system configuation file.
The rest of the 7 CPUs are cleared and deadstarted from CPU0.

INIT: SINGLE USER MODE
*******************************************************************************
UNICOS Release 8.0.4.2
Cray EL98 (sn5411 – gaff)
*******************************************************************************gaff#
At this point the root filesystem is mounted from the main disks. Some memory management/scheduling settings are printed.Unicos reads the clock in the IOS to set the time.

And finally we are up into single user mode.

 

 

init 2 would now take the system to multiuser mode.

Unicos param file

This file resides on the IOS disk and is passed with the kernel to the vector CPUS during the boot sequence. The file describes the hardware as seen from Unicos. The description of the filesystems is used by Unicos to build the disk and filesystem nodes on the root partition. This is the format for systems running Unicos 8 or later, the previous format for unicos 7 and below, was very different.
