Make sure all the cables are seated, and the I/O cards as well.<BR /><BR />Check the logs of the Mod 20 by attaching a null modem cable or serial terminal to the terminal connector. The settings should be 9600/N/1 VT100 mode.<BR /><BR />post the logs since the reboot here.<BR /><BR />also, was the Mod 20 reset at the same time as the server? if so, you may need to reboot the D370 to make the disks show up. the Mod 20 sometimes takes longer than the server to boot up.<BR /><BR /><BR />Josh Mon, 13 Dec 2004 15:27:26 GMT https://community.hpe.com/t5/disk-enclosures/what-s-wrong-with-our-system/m-p/3441588#M14590 Joshua Scott 2004-12-13T15:27:26Z
