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.

Comment 2 Gris Ge 2017-08-08 02:24:43 UTC

Patch has been sent to upstream for review:

https://github.com/libstorage/libstoragemgmt/pull/290

Comment 3 Gris Ge 2017-08-08 02:25:20 UTC

Root cause:

    When query VPD83 of Dell virtual floppy, it returns a STANDARD
    INQUIRY instead of VPD page, and this is not clarified by SCSI SPC-4
    or later version.

    [fge@dell-pe1950-06 ~]$ sudo sg_vpd --page=0x83 /dev/sdc -vvv -H
    open /dev/sdc with flags=0x800
    Device Identification VPD page:
        inquiry cdb: 12 01 83 00 fc 00
          duration=1 ms
        inquiry: pass-through requested 252 bytes but got 36 bytes
    invalid VPD response; probably a STANDARD INQUIRY response
    First 32 bytes of bad response

Gris,
Looking at lsmcli code it seems the warning is expected, but can you add a newline there so it does not throw everything off?

Comment 6 Gris Ge 2017-10-13 09:29:22 UTC

The warnning is in stderr, you may through it to null:

lsmcli 2>/dev/null
