I've built our SLES9 rescue system as a read-only mdisk that multiple guests can LINK and boot from simultaneously but have their read-write file systems in ramfs using part of their memory.
Works very well. It's not like knoppix since the filesystems aren't compressed on the mdisk but it'll do until squashfs comes with zSeries SLES. I have a script that copies the SLES9 on which it runs to a single mdisk and then modifies the copy, tweaking it to be a rescue system. My rescue system automatically assumes the failed SLES9 guest's "identity" (hostname, IP addrs, TSM client config, etc); that way my Putty ssh session definitions for each guest are still valid and my LDAP userid/pw works as usual to login to the rescue system. An it makes it easy to have Tivoli Storage Manager (TSM) restore files since the server thinks the rescue system is the failed guest and hence authorized to ask for its own files. -------------------------------------------------------- This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.
