Thank you Dr. Schwartzkopff, I should have initially been more clear in regards to this. And for that, I apologize. When it comes to scripting, I'm rather new myself. However, I have learned much and have tweaked out my script. I now have a working RA for tgtd. But it is the minimum for what it needs to run. It is also not universal. Here is a copy of the latest script that I have created -> http://www.nabble.com/file/p21668200/tgtd tgtd script . It is missing parameters that will allow this script to be universal. An associate of mine as well as myself will be diligently working on this script and perfecting it over the course of the next few weeks.
For more clarification, there are actually three packages that you can use for iSCSI. There is Open-iSCSI, iSCSI Enterprise Target, and Linux Target Framework (tgt). We are using Linux Target Framework (tgt). Here is a site that may give you a little more insight -> http://www.cyberciti.biz/tips/howto-setup-linux-iscsi-target-sanwith-tgt.html TGT . Unfortunately, we are stuck using the Linux Target Framework. I have been told before I was involved with this project that CentOS has this as a standard, although it is in fact possible to compile another package. And in regards to your question about DRBD? We are using it to replicate the data between the two targets (only) and we will be using heartbeat to monitor and control the nodes. Ideally, that is how we would like things to happen. Once again, thank you for all your help. I hope to learn much from you and many others on this forum. Michael Schwartzkopff wrote: > > Am Freitag, 16.
