Thanks for the mail, I am out of the office, and have limited access to email, until May 24th but will reply to your messages as soon as I can. Have a Great Day!! JWS ----------- Original message follows ----------- Hi We have a SAN Data Gateway 2108-G07 installed. An AIX server is connected through a brocade SAN switch to the SAN Data Gateway. Connected to this Gateway are 4 LTO devices. We seem to have installed the 2108-G07 ok , but nevertheless the LTO drives can not be "seen" from the AIX server !!!!!!? any ideas ?????? Does this brocade switch needs to be identified on the SAN Data Gateway (via StorWatch - SAN Data Gateway Specialist software) and the AIX server as well ??? any additional comments ?? thanks in advance Ruud van Ruler, Shell Services International BV - ISES/31 Our Central Data Storage Management home page: http://sww2.shell.com/cdsm/ > Room 1B/G01 > Dokter van Zeelandstraat 1, 2285 BD Leidschendam NL Tel : +31 (0)70 - 3034644, Fax 4011, Mobile +31 (0)6-55127646 Email Internet: [EMAIL PROTECTED] [EMAIL PROTECTED] R.vanRuler
