Flashing firmware on SunFire T2000

Not so long ago I had to flash firmware on SunFire T2000. It’s not a complicated thing. I need to do something with Service Controller and in the process I found out that there is no scadm utility on T2000. Why? I am not completely sure. Maybe someone can chime in. It’s probably because T2000 [...]

OpenBoot: All CPUs failed or disabled

Disabling MPxIO for onboard disks

I was configuring MPxIO on Sun Fire V490. After issuing stmsboot -e command and rebooting the server, internal disks were under MPxIO’s control. This was not something I wanted and I needed to disable it. In order to do so I had to edit /kernel/drv/fp.conf file and tell Solaris not to enable MPxIO on internal [...]
