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the product is no longer active in Red Hat Bugzilla.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.
*** Description of problem:
FAT32 filesystems on virtio-scsi disk and cd-roms cannot be read if the device has LUN > 0.
*** Version-Release number of selected component (if applicable):
OVMF-20140822-4.git9ece15a.el7
*** How reproducible:
100%
*** Steps to Reproduce:
1. start an OVMF virtual machine with a virtio-scsi disk or cd-rom having
nonzero LUN (eg. LUN==1)
2. the disk image should contain at least one FAT32 partition, or, if using a
cd-rom, the cd-rom should contain a FAT32 ElTorito boot image
3. Enter the UEFI shell, and issue "dir" on the appropriate FSx: handle
*** Actual results:
The FAT32 filesystem on the disk or cd-rom is not recognized, and the OVMF debug log contains the following:
ScsiDiskRead10: Check Condition happened!
ScsiDisk: Sense Key = 0x5 ASC = 0x24!
ScsiDiskRead10: Check Condition happened!
ScsiDisk: Sense Key = 0x5 ASC = 0x24!
ScsiDiskRead10: Check Condition happened!
ScsiDisk: Sense Key = 0x5 ASC = 0x24!
ScsiDiskRead10: Check Condition happened!
ScsiDisk: Sense Key = 0x5 ASC = 0x24!
FatOpenDevice: read of part_lba failed Device Error
*** Expected results:
The filesystem should be recognized; no SCSI errors should be reported.
