    As Mike mentioned, when you boot from CD it shouldn't start volume manager processes.

    However, you will have issues when you go to reboot from disk after changing the password, as the shadow file will not be in sync between the two mirrors, so this could cause corruption.

    If you're purely trying to recover the root password and have access to perform vxvm operations, it would probably be easiest to:

    - detach/remove rootmirror plexes in rootdg

    - boot from cd to reset root password on rootdisk

    - boot from disk

    - recreate/reattach rootmirror to rootdg

    If you don't have access to perform vxvm operations, then you'll need to unencapsulate - see the following technote:

    TECH157465: 3 ways to unencapsulate (including manual unencapsulation)

    You will need to reencapsulate once you've booted back onto disk.

Hi Mike, Thanks for the response. After Step 10, when we reboot the system, the system may be going in cyclic reboot or panic mode because there is different password in root and root-mirror disks. I have come across a procedure where it is done in other way(Rebooting wihtout veritas environment) . http://www.linuxmisc.com/3-solaris/a73c709b615f83d3.htm http://www.symantec.com/business/support/index?page=content&pmv=print&impressions=&viewlocale=&id=TECH71339 Can you kindly check and provide your valuable comments. Thanks in Advance. Regards, Shailendra Kumar Mangal
