Report the current speed and duplexity of a NIC, in this case, hme0

ndd -set /dev/hme instance 0
ndd -get /dev/hme link_speed
ndd -get /dev/hme link_mode

Link speed:

• 0 means 10mbit.
• 1 means 100mbit.
• 1000 means 1000mbit.

Link Mode:

• 0 means half duplex.
• 1 means full duplex.

Setting the following in /etc/system forces all hme interfaces to be forced 100mbit Full Duplex.

set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_100fdx_cap=1

To set only specific interfaces on boot, you need to run ndd -set on boot, as /etc/system doesn’t handle specific hme1/hme2 interfaces.

From the command line, to make hme1 100mbit Full Duplex:

ndd -set /dev/hme instance 1
ndd -set /dev/hme adv_autoneg_cap 0
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_100fdx_cap 1

Example: Ultra 1. Root Disk is in c0t0d0s0 and needs to be moved to c0t1d0s0 so a full height disk can be put in c0t0 (the bottom sled).

Add a 2nd disk in the slot you want to move to.

boot -r or drvconfig;devlinks;disks;format and see if the disk is there.

Change /etc/vfstab, shutdown, move disks. boot up.

at openboot :”boot disk1:a” and “setenv boot-device disk1:a”

Reboot again to get savecore and dumpadm happy.

Normally, if a Sun box is booted with a keyboard attached and then you remove it once the machine is up, the machine drops to openboot. To stop this, add to

/etc/system

set abort_enable=true

/etc/default/kbd

KEYBOARD_ABORT=disable 

cp flash*latest /
chmod 755 /flash*latest
drop to OpenBoot
Power off
Move JP2 to 2+3
Power on
Stop A
copy down output of printenv
boot disk /flash-update-ultra5/10-latest
version
poweroff
Move JP2 to 1+2
Delete the flash update files.

/usr/sbin/snoop is very handy for telling you what’s going on TCP, NFS wise.

d10|-d20   c1t0d0s0
   |-d30   c1t2d0s0

d10 is the main mirror with d20 and d30 as the submirrors.
d20 is the existing root fs, mounted as we start.
d30 is a partition the exact same size as d20, but blank.
