Solaris 7 Sun Hardware Platform Guide

Trouble Booting?

If your system does not boot, check that:

Your boot-device environmental variable is correctly set to your boot device.

The FCode revision level is at 1.33 or higher if you are attempting to boot through an FC/S SBus Card. To check the FCode revision level, refer to "Checking the FCode Level of Your FC/S SBus Card".

Checking the FCode Level of Your FC/S SBus Card

Determine your FCode level. Type the following at the ok prompt:

ok setenv fcode-debug? true 
ok reset
ok show-devs

When you type the show-devs command, you should see output similar to this:

.
.
.
/iommu@0,10000000/sbus@0,10001000/le@1,c00000
/iommu@0,10000000/sbus@0,10001000/SUNW,soc@0,0
/iommu@0,10000000/sbus@0,10001000/ledma@4,8400010
/iommu@0,10000000/sbus@0,10001000/SUNW,bpp@4,c800000
/iommu@0,10000000/sbus@0,10001000/espdma@4,8400000
/iommu@0,10000000/sbus@0,10001000/SUNW,DBRIe@2,10000/mmcodec
/iommu@0,10000000/sbus@0,10001000/SUNW,soc@0,0/SUNW,pln@a0000800,201cac11
/iommu@0,10000000/sbus@0,10001000/SUNW,soc@0,0/SUNW,pln@a0000800,201cac11/SUNW,ssd

Look at the output from the show-devs command and find the lines for the FC/S card(s) that is attached to the SPARCstorage Array that you want to boot from.

The output for an FC/S card will be the lines containing soc@x,x similar to:
```
/iommu@0,10000000/sbus@0,10001000/SUNW,
soc@0,0
/iommu@0,10000000/sbus@0,10001000/SUNW,soc@0,0/SUNW,pln@a0000800,201cac11
/iommu@0,10000000/sbus@0,10001000/SUNW,soc@0,0/SUNW,pln@a0000800,201cac11 SUNW,ssd
```

To determine which version of FCode is in the FC/S card, type:
```
ok cd 
short_path
ok sccsid type
1.33 95/04/19
ok device-end
```
where short_path is the shortest line containing soc@x,x from the output. Using the previous output as an example, you would enter:
```
ok cd /iommu@0,10000000/sbus@0,10001000/SUNW,soc@0,0
ok sccsid type
1.33 95/04/19
ok device-end
```

If the FCode version is not at 1.33 or higher you must upgrade to the minimum FCode level.

Note -

You can upgrade your FCode after installing the Solaris 7 software.

The following part numbers refer to the FC/S SBus Cards that contain the minimum FCode revision level to allow booting:

501-2069-07 or higher
501-2553-03 or higher

Reset your OBP environment variable fcode-debug?
```
ok setenv 
fcode-debug? false
ok reset
```
