The same goes for peer to peer tapes too. I have a hard time to convince my management and storage guys that I really need a SECOND set of SMF data. One set to do write and if RC=00 everywhere, repeat on second SMF set. This is because when we get a channel error resulting in 613 abend or so, every errors and halfwritten records written on the local site are also repeated at the other site. I then sit with two sets of useless SMF data residing at 2 sites. I made a breakthrough when I asked them to switch off local tapes so I can reread my SMF tapes from remote site to prove that the second set at remote site are ALSO damaged. Then only they see the need for duplicate SMF tapes. I got my extra SMF tapes with recovery procedures simplified. ;-) Groete / Greetings Elardus Engelbrecht ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
