<----- snip -----> I was told that in order to do this the secondary volume labels' must be clipped before I can bring them online but by clipping them I also loose the primary-secondary volume relationships. Besides using another lpar or other 3rd party utilities to run the backups, how does one handle this situation? <----- snip ----->
>From "Hitachi Freedom Storage™ Lightning 9900™ V Series Hitachi TrueCopy – S/390® User and Reference Guide" <snip> The RCU does not allow a TC390 R-VOL to be online and rejects all host-requested read and write I/O operations for a TC390 R-VOL. The TC390 R-VOLs must be offline during normal TC390 operations. Note: TrueCopy – S/390® provides a special R-VOL read option (see section 2.2.4) which allows read-only access to the R-VOL while the pair is suspended. If you need write access to a TC390 R-VOL, you must delete the pair. 2.2.4 R-VOL Read Option For additional flexibility, TrueCopy – S/390® offers a special R-VOL read option. The Hitachi Data Systems representative enables the R-VOL read option on the RCU (mode 20). The R-VOL read option allows you to read a TC390 R-VOL only while the pair is suspended, that is, without having to delete the pair. The RCU will allow you to change only the VOLSER of the suspended R-VOL, so that the R-VOL can be online to the same host as the M-VOL while the pair is suspended. All other write I/Os will be rejected by the RCU. The MCU copies the M-VOL VOLSER back onto the R-VOL when the pair is resumed. When the R-VOL read option is not enabled and/or the pair is not suspended, the RCU rejects all read and write I/Os to a TC390 R-VOL. Note: If you need write access to an R-VOL, you must delete the pair. Note: For 2105 controller emulation, the CSUSPEND command to the R-VOL of a suspended TC390 pair will be rejected when the TC390 R-VOL read option is used. <snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
