Solaris 10 not Starting

System was not coming up, svc-system-sysevent service was not coming up causing the entire system to stay wwithout any network services.

Trying to bring the service online fails and its logs show nothing.

metastat showed the the three metadevices d0, d1, d3 need maintenence
df -h shows root as /pseudi/blahbla which is the md root device path from /etc/system

any attempt to something that writes to the root say “read only filesystem”

for d0
d10 and d20
d10 need to be replaced saying use mtereplace d10 c1t0d0s0 <new device>
and d20 shows needs to be synced, use metasync d20

same for d12 d22 and d13, d23

to solve this problem
metasync d20
nothing happens until we do
metareplace -e d10

Now the mirror start syncing.
repeated for all metadevices
fsck after completion
reboot, everything is now working fine.

NIS

While creating NIS master server on Solaris, with the default settings on a freshly installed system, I got the following error;

root@master# ypinit -m

In order for NIS to operate sucessfully, we have to construct a list of the
NIS servers.  Please continue to add the names for YP servers in order of
preference, one per line.  When you are done with the list, type a <control D>
or a return on a line by itself.
next host to add:  master
next host to add:

The current list of yp servers looks like this:

master

Is this correct?  [y/n: y]  y

Installing the YP database will require that you answer a few questions.
Questions will all be asked at the beginning of the procedure.

Do you want this procedure to quit on non-fatal errors? [y/n: n]  y
The yp domain directory is /var/yp/tps.local
Can we destroy the existing /var/yp/tps.local and its contents? [y/n: n]  y
There will be no further questions. The remainder of the procedure should take
5 to 10 minutes.

*** Error code 1
The following command caused the error:
if [ ! 1 ]; then make   -k all; \
else make  -k all NOPUSH=1;fi
make: Fatal error: Command failed for target `k’
Error running Makefile.

Searching for the error on google was useless. Finally I found the cause of the problem.
make -k all, makes all targets i.e. maps.
If you follow the output, /etc/ethers, /etc/bootparamas, and /etc/netgroups do not exist, and thus make -k all fails because some targets did not complete. -k in make causes it to continue to non-dependent targets, if one target fails.

I did the following to fix this;
cp /var/yp/Makefile /var/yp/Makefile.orig
edit the Makefile
remove ethers, bootparams and netgroup from the target all.
ypinit -m again is then successful.
