Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

.ReaR is now fully supported also on the 64-bit IBM Z architecture Basic Relax and Recover (ReaR) functionality, previously available on the 64-bit IBM Z architecture as a Technology Preview, is fully supported with the `rear` package version 2.6-9.el8 or later. You can create a ReaR rescue image on the IBM Z architecture in the z/VM environment only. Backing up and recovering logical partitions (LPARs) is not supported at the moment. ReaR supports saving and restoring disk layout only on Extended Count Key Data (ECKD) direct access storage devices (DASDs). Fixed Block Access (FBA) DASDs and SCSI disks attached through Fibre Channel Protocol (FCP) are not supported for this purpose. The only output method currently available is Initial Program Load (IPL), which produces a kernel and an initial ramdisk (initrd) compatible with the `zIPL` bootloader.
