      What were you trying to do that didn't work?

      When restarting multipathd on a system used for FC and NVMe-FC FC testing, I have observed the following warnings:

      Aug 14 09:35:29 storageqe-01.fast.eng.rdu2.dc.redhat.com 55-scsi-sg3_id.rules[10270]: WARNING: SCSI device dm-6 has no device ID, consider changing .SCSI_ID_SERIAL_SRC in 00-scsi-sg3_config.rules

      Aug 14 09:35:29 storageqe-01.fast.eng.rdu2.dc.redhat.com 55-scsi-sg3_id.rules[10308]: WARNING: SCSI device dm-3 has no device ID, consider changing .SCSI_ID_SERIAL_SRC in 00-scsi-sg3_config.rules
      Aug 14 09:35:29 storageqe-01.fast.eng.rdu2.dc.redhat.com 55-scsi-sg3_id.rules[10310]: WARNING: SCSI device dm-2 has no device ID, consider changing .SCSI_ID_SERIAL_SRC in 00-scsi-sg3_config.rules

      I do not recall seeing this on the same system with RHEL-9. Additionally, the message references 55-scsi-sg3_id.rules but I was only able to find 61-scsi-sg3_id.rules:

       

      1. find /lib/* -name scsi-sg3_id.rules
        /lib/udev/rules.d/61-scsi-sg3_id.rules
         
      2. rpm -qf /lib/udev/rules.d/61-scsi-sg3_id.rules
        sg3_utils-1.48-5.el10.x86_64
         
      3. rpm -ql sg3_utils | grep udev
        /usr/lib/udev/fc_wwpn_id
        /usr/lib/udev/rules.d/40-usb-blacklist.rules
        /usr/lib/udev/rules.d/61-scsi-sg3_id.rules
        /usr/lib/udev/rules.d/63-fc-wwpn-id.rules
        /usr/lib/udev/rules.d/63-scsi-sg3_symlink.rules
        /usr/lib/udev/rules.d/65-scsi-cciss_id.rules
         
        If I removed sg3_utils, I no longer see the warnings when restarting multipathd.

        Please provide the package NVR for which bug is seen:

      sg3_utils-1.48-5.el10

      kernel-6.10.0-15.el10

      6.10.0-15.el10
