Don, You likely need the updated RPM that corrects this problem: SO10302 - VMTLI: MOUNT FAILS, TAPE DRIVE DETACHED AFTER ATTACH
JR (Steven) Imler Sr. Software Engineer | Mainframe Division Broadcom office: +1 571.401.8685 2291 Wood Oak Drive | Herndon, Virginia 20171 [email protected] | broadcom.com -----Original Message----- From: Linux on 390 Port <[email protected]> On Behalf Of Donald Russell Sent: Tuesday, October 26, 2021 04:35 PM To: [email protected] Subject: Fwd: udev detaching devices? RHEL7.9 running on zVM 7.1 with VMTAPE. A vmtape mount command successfully mounts a tape and “gives” the tape drive to Linux. Linux promptly detaches the drive. I thought it was due to udev rules, but I don’t see what’s wrong. I thought maybe it was related to blacklisted device numbers, but cio_ignore shows nothing is blacklisted. How can I get more information about why the tape drive is detached? The udev rules look specific to IBM drives, and these are Secure Agent drives…maybe no rules covers it so Linux says “oh no you don’t, you’re not bringing that in here”? :-) How can I see the device info in order to make a suitable udev rule? #udevadm monitor monitor will print the received events for: UDEV - the event which udev sends out after rule processing KERNEL - the kernel uevent KERNEL[192616.914861] add /devices/css0/0.0.0061 (css) KERNEL[192616.914901] add /devices/css0/0.0.0061/0.0.0478 (ccw) UDEV [192616.955020] add /devices/css0/0.0.0061 (css) UDEV [192616.963492] add /devices/css0/0.0.0061/0.0.0478 (ccw) KERNEL[192617.916677] remove /devices/css0/0.0.0061/0.0.0478 (ccw) KERNEL[192617.916699] remove /devices/css0/0.0.0061 (css) UDEV [192617.917073] remove /devices/css0/0.0.0061/0.0.0478 (ccw) UDEV [192617.917191] remove /devices/css0/0.0.0061 (css) The above kernel/udev events happen when I vmtape mount --vol <x> The tape is mounted, attached to linux then immediately removed/detached The relevant rules file I have is: #cat 99-vmt_event.rules SUBSYSTEM=="ccw", ACTION=="add", RUN+="/usr/bin/vmtuevent attach %k" #SUBSYSTEM=="ccw", ACTION=="remove", RUN+="/usr/bin/vmtuevent detach %k" KERNEL=="[nr]tibm[0-9]*", ACTION=="add", KERNELS=="[0-9A-Fa-f.]*", RUN+="/usr/bin/vmtuevent mount %b %n" #KERNEL=="[nr]tibm[0-9]*", ACTION=="remove", RUN+="/usr/bin/vmtuevent umount %n" #KERNEL=="btibm[0-9]*", ACTION=="remove", RUN+="/usr/bin/vmtuevent umount %n" I commented out the remove items and restarted the server…. the remove events still happened. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www2.marist.edu/htbin/wlvindex?LINUX-390 -- This electronic communication and the information and any files transmitted with it, or attached to it, are confidential and are intended solely for the use of the individual or entity to whom it is addressed and may contain information that is confidential, legally privileged, protected by privacy laws, or otherwise restricted from disclosure to anyone else.
