Thanks very much to both of you for taking the time to respond to my query. I'll try to post details of this activity after I get a new replacement disk. Wish I had a place to experiment . We're having a little trouble getting the replacement disk on-site so my feedback may take a few days.

I will try to locate and read The section in "Veritas Volume Mnager Trouble shooting guide" (section Re-Adding and replacing Boot Disks). Thanks again!
