SCU reserve/release device
I have a problem without solution.
We have a MSL5052 tape library. This library have a robot "/dev/changer/mc0" and four drives "/dev/ntape/tape11_d1, /dev/ntape/tape12_d1, /dev/ntape/tape13_d1 and /dev/ntape/tape14_d1".
We have two ES40 in a Tru64 Cluster, version 5.1 and many Windows 2000. All these machines use the tape library.
The problem occurs when the Cluster Tru64 is doing the daily backup with the VDUMP command. My script is like this, first i move the control of the tape library to the member who is going to do the copy. Second I reserve the driver that I am going to use. Third I VDUMP the filesets. Fourth I release the driver because anyone can use it after the copy. I use these commands:
/sbin/drdmgr -a server=sc01ud0601 /dev/changer/mc0
scu -f /dev/ntape/tape14_d1 reserve device
/sbin/vdump -0 -Nu -f /dev/ntape/tape14_d1 /cluster/members/member1/boot_partition
/sbin/vdump -0 -Nu -f /dev/ntape/tape14_d1 /cluster/members/member2/boot_partition
...
...
/sbin/vdump -0 -Nu -f /dev/ntape/tape14_d1 /oracle/8i/orasoft
scu -f /dev/ntape/tape14_d1 release device
I don't know wher is the problem because when i see the log of the backup i see this error
vdump: unable to write to device ; [5] I/O error
vdump: unable to prompt input for retry on device; [25] Not a typewriter
This is the log of the VDUMP:

Re: SCU reserve/release device
This error message comes out if there is a script that wants to access tape13 and there is no tape there or the tape is full.
Check your scripts and also check the error log

Re: SCU reserve/release device
from your log it looks like you haven't exceeded the size of the tape, unless you have used the tape before and appending your dump to its contents, this might lead to suspect that the tape got full.
Then I think it is one of 2 options, the tape got unloaded so the script didn't find it, or you got an error with the SCSI connections.
My suggestions is try to use a new tape and dump a lot of save sets to it, maybe try to dump /usr directory several times and see if this problem persists. Also check the errorlog file, it will tell you if there was a SCSI CAM bus error or something like that.
