| Hello Everyone, One of our servers is showing a strange issue, let me paste the output Code: root # uptime 4:37pm 3 users, load average: 0.00, 0.04, 0.04 Its been running since months but you can see after time there isn't any output like up 191 days(s). Even the who command with b and r option isn't giving any output. Code: root # who -b root # root # who -r root # the date command displays correct output. I am not sure but is it because someone has played with utmpx and wtmpx files, is reboot the only solution we have. Can anyone help us since we don't intend to reboot the server for such a reason and also no one has complained till yet. | 176 | | | | ||

1)What can I do if Solaris won't boot?
You need to boot from your install CD. Insert the Solaris Software CD in your CDROM drive. If your CDROM drive/BIOS isn't bootable, first insert the "Device Configuration Assistant" (DCA) diskette. At the "Boot Solaris" menu, choose "CD."
At the "Type of Installation: Interactive or JumpStart" menu, type "b -s"
Or, after the video configuration, network, time and date you'll notice one of the menu's has a button: [Exit] Select Exit and, when it asks you again "do you want to exit?," just say yes.
Once you're at the UNIX root prompt #, you can mount the boot drive with "mount /dev/dsk/c0t0d0s0 /mnt"" and view anything wrong with the boot drive (omit the "t0" for ATAPI).
2)How do I restore the Solaris boot block without reinstalling?
This may happen when installing a boot manager that comes with another operating system (such as LILO from Linux) or an after-market multi-OS boot manager. These sometimes trample's active partition, which in our case is Solaris. Also, moving the Solaris partition with a partition manager program such as Partition Magic requires reinstalling the Solaris boot block. Before taking these steps, first verify the Solaris partition is active. If it isn't, just make the Solaris partition active and reboot. Otherwise follow the steps below.
1. Boot from CD-ROM and get the root prompt, #, as described in the previous question, 7.1.
2. Determine the controller, disk number, and partition. The boot disk is /dev/rdsk/c?t?d?p? where ? is the controller #, target ID, and disk #, and partition #. Omit "t?" for ATAPI E.g., /dev/rdsk/c0d0p0
3. Verify it's the correct device correct with prtvtoc for the drive: This is VERY important; if it's wrong, you you may hose another partition: prtvtoc /dev/rdsk/c0t0d0p0 (omit "t0" for ATAPI, always use p0, which means the "entire drive"). The prtvtoc prints out the map for the Solaris partition on the hard drive, if found. The partitions shown on the output are actually "slices" within the Solaris partition.
4. Restore the boot block as follows:
/sbin/fdisk -b /usr/lib/fs/ufs/mboot (raw disk dev)
E.g., for SCSI it might be:
/sbin/fdisk -b /usr/lib/fs/ufs/mboot /dev/rdsk/c0t0d0p0
(omit "t0" for ATAPI)
5. Finally, remove your CDROM and diskette media and type "/sbin/shutdown -i6" to reboot. The Solaris Multiple Device Boot Menu should appear after rebooting. If not, you can always to an upgrade (re-)install.
Note: This procedure does NOT make your Solaris partition active again (sometimes needed after installing another operating system, such as Windows, on the same disk), it just writes to your bootblock IN your Solaris partition. To learn more about the Solaris boot process, read the boot(1M) man page.
3)How do I logon as root if the password doesn't work anymore?
Regaining control of a Solaris x86 system where the root password has been lost can be accomplished by the following steps. Note that any savvy user can do this with the proper CD-ROM and diskette. Therefore, of course, physical security of a system is important for machines containing sensitive data.
1. Insert installation boot diskette and installation CD-ROM for Solaris x86.
2. Boot system from the installation floppy and select the CD-ROM as the boot device.
3. Type "b -s" (instead of typing 1 or 2 from the menu) and it'll drop you straight to a root shell, #, (and you'll be in single-user mode).
4. At the root prompt, #, key in the following commands, which will create a directory called hdrive under the /tmp directory and then mount the root hard drive partition under this temporary directory.
5. mkdir /tmp/hdrive
6. mount /dev/dsk/c0t0d0s0 /tmp/hdrive #SCSI; for ATAPI, omit "t0"
7. To use the vi editor, the TERM variable must be defined. Key in the following commands.
8. TERM=at386
9. export TERM
10. Start vi (or some other editor) and load /tmp/hdrive/etc/shadow file:
11. vi /tmp/hdrive/etc/shadow
12. Change the first line of the shadow file that has the root entry to:
13. root::6445::::::
14. Write and quit the vi editor with the "!" override command:
15. :wq!
16. Remove the floppy installation diskette, and reboot the system:
17. /sbin/shutdown -i6
18. When system has rebooted from the hard drive, you can now log in from the Console Login: as root with no password. Just hit enter for the password.
