Not only possible put inmost cases much faster that copy the data using unix commands such as pax of copytree. Here is the fine manual says about this: z/OS Distributed File Service zFS Administration Version 2 Release 1 Increasing the size of a compatibility mode aggregate Copying the physical blocks of the aggregate to a larger data set Another method to increase the size of a zFS aggregate is to copy the physical blocks of the aggregate to a larger data set using the DFSMS REPRO command. This approach is normally faster than using the pax command. However, do not format the target zFS data set before using the REPRO command. Figure 10 on page 34 shows an example of this approach. [snip] With this approach, the new VSAM linear data set must not be formatted as an empty zFS file system before the REPRO command is used. (If the new data set was formatted, the REPRO would copy blocks to the end of the primary allocation, not the beginning. The data blocks being copied contain all the file system data and the file system information, so formatting is not necessary.) Neither file system needs to be mounted. REPRO uses native VSAM calls to read and write the blocks. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
