I have a new Dell PowerEdge 2950 running CentOS 5.0 out-of-box and a Dell MD3000i. I am new to iscsi and, with google and included documentation, am having a heck of a time trying to get the RAID volumes I have created on the 3000i to be seen by the OS as usuable drives. I have printed out SMcli and iscsiadm documentation. I have asked on the linux-poweredge at dell.com site, too. Many leads, but there is something - be it a command, setting, or whatever else, that is just eluding me. How do I get the RAID devices seen on my C 5.0 box? The setup is currently on an isolated LAN and has no valuable data - all testing and experimenting by me, for now, to learn how it works, before putting it into production. Thanks for any and all leads. Scott

Did you define any LUN masks or CHAP authentication on the MD3000i? The MD3000i has multiple iSCSI interfaces for fail-over mode, did you install the dm-multipath? How is that setup?

I'll dig out some notes and post them later tonight. -- ------------------------------------------------------------------------ Jim Wildman, CISSP, RHCE jim at rossberry.com http://www.rossberry.com "Society in every state is a blessing, but Government, even in its best state, is a necessary evil; in its worst state, an intolerable one."
