How I can solve the problem by having one drive available in Tape Library?, I send the following message in the Activity Monitor
Limit Has Been Reached for requested resource

you don't say what resource.
your storage unit may have a limit of say 2 drives and both drives are in use so the job which is suppose to use that storage unit cannot use a third drive. so if you have 2 drives and you say multiplex of say 5 concurrent jobs per drive then 10 jobs can run at once the 11th job would queue waiting for one of the two drives to have less then 5 jobs running.
Its all based on what you have setup you storage units for.
you could also be limited by the number of jobs a policy is allowed to run, or by the number of jobs a client is allowed to run. As your message says resource I am assuming it is a limit on the number of drives and how may jobs per drive set in your storage unit.

I am attaching the image with the settings Storage Unit Hcart3
The robotic library has LTO4 Drive and should be of type HCAT, but because we still have LTO3 tapes and type Hcart3 in Netbackup
Can you please tell me when to perform additional configuration on the Storage Unit?
or should it be done to level policy?

If you want more jobs to run to these two tape drives tick the "enable multiplexing" box and select a figure (such as 6) in the Maximum Streams per drive section below it.
Next you need to edit the schedules in your policies to set the multiplexing to 6 to match
Also, if any client run more than one stream each then on the Master Servers host properties - General tab, make sure the maximum jobs per client is set to a suitable level to allow them to run multiple jobs.
Using the figure 6 as aoutlined here will allow 6 jobs to run to each tape drive at a time so 12 jobs in total can run
Hope this helps

Maximum concurrent write drives is set to 2 - this is what is limiting the jobs from using another tape drive - this storage unit is set to only use 2 drives - so any policy that is using this storage unit - all get grouped together and are only allowed to use 2 tape drives at once ( if you increase to 3 it can use 3 hcart3 tape drives at once)
You can also increase the number of jobs running by enabling Multiplexing - this say how many jobs can run to one tape drive at a time. So here with 2 drives if you increase the Maximum streams per drive to 5 with just the 2 jobs - you can have 10 jobs running at the same time to the 2 tape drives.

Modify values in propertiers Host-> Global Atributtes-> Maximun job Maximun per client and backup copies of 1 to 10, but now I appear queued job and I get the Hcart storage unit 3 in use, but the drive does not have mounted tapes.
Why show that the storage unit is busy, if I have one drive available?

means they are both being used. Sometimes Recorded Media ID does not show in the GUI, not sure why but I've seen that. You can run command vmoprcmd which I find is more accurate.

You seem to have 2 Media Manager Storage Units defined. Do you have more than one media server?
Please show us all you STU's. Run the following from cmd on the master server:
<install-path>\veritas\netbackup\bin\admincmd\bpstulist -U
as well as resource allocations:
<install-path>\veritas\netbackup\bin\admincmd\nbrbutil -dump
Post output of these commands.
Sorry - if I look at you server name it seems to be a Solaris machine?
The path to these commands on a Unix server will be /usr/openv/netbackup/bin/admincmd
12-14-2011 12:17 PM
commands are executed:
C:/archivos de programas/veritas/volmgr/bin/vmoprcmd
C:/archivos de programas/veritas/netbackup/bin/admincmd/bpstulist -U and finally
C:/archivos de programas/veritas/netbackup/bin/admincmd/
The server has the roles of master and media server running Windows 2003x64
How I can guarantee that they are used both drive when running the backup job?
