MirrorDisk

Constance — Wed, 13 Mar 2002 19:19:10 GMT

I have very little knowledge of unix/hpux. I have been tasked with installing MirrorDisk UX on a 10.20 system. I login as root. I have the CD's and a Codeword for MirrorDisk. The system has 2 identical disks of which one is used and the other is unused.

When I mount the and type swinstall the resulting GUI does not show MirrorDisk in the list of available software. When I do "swlist -s /mnt/cd" MirrorDisk does show up in the list.

Also, I have no idea what to do in the system to prep the unused disk to be used as a mirror.
Obviously I'm in way over my head here, can anyone help?

Thanks,
Constance Cate

First of all did you enter the codeword in the swinstall window to enable MirrorUX ? In swinstall window, goto Action->Add-New-Codeword and another window will pop-up for you to key in the codeword, customer id, etc. Once that is done, you should be able to see MirrorUX in the swinstall list.

Hello,

When you go into the swinstall GUI, go to Actions --> Add new Codeword and enter in your information. You should then be able to see your MirrorDisk/UX software selection. As for the PRoceedures for mirroring your disks, see the attached document our group has typed up. This is for mirroring vg00, but leave off the boot area commands for data disks.

Hope this helps

Chris

If you are happy to go ahead and do this, then first ensure you have a good system backup, and know how to recover the system, just in case.
You then need to run swinstall, anbd select Install CodeWord, and put in th ecodeword.
Tis should then allow you to see the MirrorDisk prodiuct.
select it, install it, and then have a read of:

Managing Systems and Workgroups: A
Guide for HP-UX System Administrators

availabale at:
http://docs.hp.com/hpux/onlinedocs/B2355-90742/B2355-90742.html

and under:
Managing File Systems you will find a section:

Managing Mirrored File Systems

which will explain ti to you.

best of luck

I did do a full backup but I have not used Ignite to create a recovery tape. That is the next task. Thanks for the link, I can use all the info I can get!
