solaris: how to recover solaris 11 root password
boot net -s
boot cdrom -s, if it ask username: root/solaris or root/password.
on x86, you need edit grub and append -s on kernel line.
after login. mount /dev/dsk/cxtxdxsx /a
if you use zfs for /, then zfs import
zfs list
zfs set mountpoint=/a rpool/ROOT/solaris
zfs mount -f rpool/ROOT/solaris
then edit /etc/shadow
remove the password section, let it looks likes.
root::15356::::::
don’t forget to reset the mountpoint back
zfs set mountpoint=/ rpool/ROOT/solaris
reboot.
how to fix ‘who -r’ shows nothing
OS: Solaris 9.
Issue: who -r won’t give you the running level. so the pkgadd won’t work.
myhost1:~ root # who -r # shows no output
Solution:
check the /var/adm/utmpx, maybe the file has been corrupted
myhost1:~ root # cd /var/adm
myhost1:adm root # vi u1.log
# paste the following content.
system boot 0 2 0000 0000 1315335814 0 0 0 Tue Sep 6 20:03:34 2011

Install Lftp on Solaris 9 manually
Yeah, there is pkg-get way.
If you don’t have pkg-get, you can follow the steps.
wget ftp://ftp.sunfreeware.com/pub/freeware/sparc/9/lftp-4.0.10-sol9-sparc-local.gz
wget ftp://ftp.sunfreeware.com/pub/freeware/sparc/9/readline-5.2-sol9-sparc-local.gz

/var/adm/wtmpx too big
How to safely clean the /var/adm/wtmpx
Solution 1 (clean everything):
# cd /var/adm
# gzip -c wtmpx > wtmpx.backup.gz
# > wtmpx
Solution 2(keep last 1000 logs):
# cd /var/adm
# /usr/lib/acct/fwtmp < wtmpx | tail -1000 > wtmpx.ascii
# /usr/lib/acct/fwtmp -ic < wtmpx.ascii > wtmpx
# rm wtmpx.ascii
The commands makes convert info from binary to ascii from wtmpx, save last 1000 lines into wtmpx.ascii file, convert the info in wtmpx.ascii to binary again, and save it into wtmpx. Finally no-needed wtmpx.ascii is removed.
Solaris: Boot archive error or corrupt
Boot archive error or corrupt
A few weeks ago, I got a little problem with my solaris box, namely solaris won’t boot because the boot archive was corrupt, *sigh*. Anyway the boot archive in solaris 10 was contain kernel module and configuration file was needed for solaris to startup the system.
Error:
module /platform/i86pc/boot_archive error 3 bad or corrupt data while decompressing file
Workaround:
Boot up your solaris in “solaris failsafe mode”, next solaris image will mount with writeable mode on “/a” mount point
rm -f /a/platform/i86pc/boot_archive
bootadm update-archive -R /a
reboot
Solaris: get global zone name from non-global zone
run the netstat -p from non-global zone, get the ip information.
check the ip. one of the ip should be global zone’s ip.
there is any commands to check ? No.
so we’d better keep a good record, like motd. or cmdb.
Solaris Patching
Busy with Solaris patching these days. some servers didn’t reboot/patch for more than 3 years.
Some tips:
1. “ERROR: LSI1030: timeout waiting for interrupt status.
ERROR: LSI1030 MPT Firmware, receive-message: issue-port-enable failed.”
Possible Answers:
1st:
{3} ok setenv auto-boot? false
{3} ok reset-all
{3} ok probe-scsi-all
sc>reset -y

contain holes – can’t swap on it.
root@home# mkfile 512m /var/swapfile
root@home# swap -a /var/swapfile
“/var/swapfile” may contain holes – can’t swap on it.
the above is ok for UFS, but not work in ZFS.
Solution:
root@home# zfs create -V 1gb rpool/swapfile
root@home# swap -a /dev/zvol/dsk/rpool/swapfile

mount: /mnt/nfs: Not owner
nfs mount: mount: /mnt/nfs: Not owner
When you get this error from a Solaris Host, because you are trying to mount an nfsV3 share with an nfsV4 client.
This occurs when you want to share an nfs from a linux host to a solaris host.
Just use the option vers=3 to avoid this problem or configure nfsV4 on the linux host.
mount -o vers=3 linux_nfs_01:/htdocs /htdocs
