Applying maintenance using MSM and doing this directly from z/OS, can the same method be used to send the dumps to support?
CSM 6.0 - z/OS supported releases -
Yes, the dump can be sent directly from z/OS to the ftp directory.
Get the dump, terse it with the TRSMAIN utility and upload it in BINARY to the ftp directory related to the case.
It should be: https://supportftp.broadcom.com/site-id/case-number/files_from_customer/
