Where did my drives go?

So operations pulled a few tapes this morning, put some tapes in and let me know when they were done.  My backups and initializations starting failing.  Seems the drives just up and disappeared:

[Critical] From: MMA@sapbck.ssmhc.com "LTO_Drive_2" Time: 4/26/2016 11:39:02 AM

[90:1004] Device address not found.

I checked via ioscan and they seemed like they were still around:

But when I checked in DP itself all teh addresses were 'bad':

I tried a soft boot of the library, hard boot of the library, and multiple ioscans.  No luck.  where'd my drives go? Why did they go? And how do I get them back?  I am trying NOT to have to reboot my CM.

Thanks

CM is HP-UX 11.31

DP is 9.06

 Oh, and I did open a ticket with support.

check for stuck BMA, CMA or RMA Processes, they can prevent DeviceScan from seeing the required Paths.

I have bounced the server so many time since then I don't think it is a process...

Re: Where did my drives go?

when you reboot the MediaServer the Processes there are gone, true that.

does your ioscan now show all required targets on the host? have maybe the serial-numbers changed?

Re: Where did my drives go?

what type of library is it? Ultrium-2 is very old now....

if you run devbra -dev locally on the HPUX host, do you see serial numbers?

Yes, ioscan show everything.  No issues at the HPUX level.  Even with DP trying the scan for new serial numbers it fails.

Re: Where did my drives go?

Shouldn't HPUX 11.31 use estape devices? What does ioscan -fNC tape give you? Have you tried removing and recreating some of the Special-Files (rmsf/insf)?

Hello

Please NOTE that s/n stored into IDB has 10 characters and s/n detected by devbra command just 8 characters. It sound familiar to me for specific libraries with DP 8.x, maybe you are suffering the same.

Please opem support call nad provide devbra output running command in debug mode 1-300

Best Regards
