PV 124T Brightstor Arcserve 11.5/Linux System Locked

I have a PV 124T and I always get a System Locked message when trying to eject a tape from the slot or eject the magazine. The only consistent way to get around the problem is to shutdown Arcserve, and power down the tape drive and restart them both.

System Info
RHEL 3 Update 6 - 2.4.21-40.ELsmp
Autoloader: PV-124T Drive: LT0-2 Version: V26.0
Left Magazine: Present
Right Magazine: Not Present
Barcode Scanner: Present
Drive Version: 1801 SCSI ID: 6
Brightstor Arcserve 11.5

I see the post from another peron regarding Veritas, sadly Arcserve doesn't have an unlock option. Dell support has told me it CA's problem and CA doesn't have an answer. We also have a 124T on a Windows 2000 server with 11.1 and it does not have this issue.

I believe that it sends this lock to the device or something, and then doesn't release it correctly becasue I can stop arcserve and it will stay locked. Until I power the loader down it won't work again generally. A few times I have been able to stop arcserve, it will be locked, start arcserve and it will be unlocked.

I have looked at mtx or another tool to nudge this thing to unlock, haven't found anthing yet.

Any advice would be appreciated.

Thanks,

Mark

Just an update in case anyone else has this problem. CA didn't really have a solution but I have found if you disable OpenManage (in my case 4.4) it tends not to be locked as often. Also a restart of the media service and it appears to work once the final inventory is done. This didn't work before when OpenMange was running.

This is the second OpenManage type problem I have found with the 124T. The first was the following errors in dmesg on boot up.

(scsi1:A:6:0): data overrun detected in Data-in phase. Tag == 0x4.
(scsi1:A:6:0): Have seen Data Phase. Length = 50. NumSGs = 1.
sg[0] - Addr 0x035508000 : Length 50
(scsi1:A:6:0): data overrun detected in Data-in phase. Tag == 0x3.
(scsi1:A:6:0): Have seen Data Phase. Length = 50. NumSGs = 1.
sg[0] - Addr 0x035508000 : Length 50

Though harmless it was annoying. And looks bad to have errors on your console all the time.

Dell replaced my changer, the SCSI card and cables and it wouldn't clear. It was escalated high enough where the Dell Linux folks had seen this with testing the 124T on OpenMange 4.5, my experience seems to suggest its in 4.4 as well. They are working on a patch for it I am told.
