Is this a LAN free backup?

[ADSM-L] Insufficient system resources exist to complete the requested
service
Hi
I have been doing some extensive testing on the entire disk storage pool
question.
The first question, is what is the feed? i.e. how many network connections
does the TSM Server have. I am assuming all your larger systems are likely
to go LAN FREE direct to tape. Also, what volume are you back
Fortunately the disk storage pools on TSM have a larger block size which
is much more suited to throughput.
Again the RAID type and read cache available will have an effect on this.
But as Allen says, you will see the performance ceiling much quicker on
SATA than FC, as random IO will have to come
An old gotcha on AIX was the ulimits file. Limiting the filesize any user
could create. Also if the filesystem was large file enabled for files over
2 GB.
These are quite old issues though.

Please
Do the client backup sessions pin the log? What is the throughput on the
actual client session and are these backups direct to disk? If the
sessions are cancelled does the system come back to life?
15 TB of SATA sounds like a lot of storage. how has this been
added/configured- What raw throughput
For this volume of data it may be better to do it via media, or if you are
going to do it via IP- I would advise deploying a dedicated network link
for that export purpose. define the IP address on the dedicated nic as the
server address. This means that traffic will be localised to the dedicated
l
The network transfer rate is very slow, are the NICs set to full duplex
and speed fixed or are they autonegotiating with the switch? What else is
passing through the TSM Server NICs at the time? Are the backups going to
disk or tape?What are those resourses doing at the time?
Also, can you get the
I would get the
logs to show mediaw/idlew?
Just let me know. And thanks!

Hi
Block size, queue depth, sequential v random read, back end
spindles/design, array cache size, other array traffic etc will all play a
part.
On an Windows system with default NTFS block size, with queue depth of 16,
on a dedicated HDS array I can quite easily sustain approx 400MBs on a

Hi
I am in process of deploying NDMP backups for NetApp filers on TSM 5.4.
I have a few questions:
How is the content actually expired?
Does NDMP NetApp actually do incremental backups, or differential?
Is there any way to create copies of the NDMP data once backed up?

Re: [ADSM-L] NDMP Help!
The backups 'sets' are full and differential.
You can create a copypool instance of a NDMP based backup.

Hi
If I want to restore files to another server, I can change the nodename on
the restore server and reauthenticate and access the files. However on the
TSM server, it changes the IP address of that Node.
If I use virtualnodename on the restore server, does it do this? As I want
to continue norma
Check that the node correctly connects and authenticates manually to the
server first. Also ensure the service is running under an account with the
correct privileges. What version of TSM Client is it?

Hi
I am running a TSM 5.4 Server, trying to backup/restore a NetApp filer
over IP to a native LTO3 tape storage pool. The backups are NDMP images,
with the TOC. The TOC goes to a separate disk storage pool.
I am experiencing terrible performance. In the region of 2 MBs for backup
and 0.2MBs resto

I have a question regarding paths for drives in a storage agent
environment:
If drives are in a library, can they be defined on the Library Manager as
drive, but ONLY have paths to the storage agent?
Or must all drives need to be pathed to the library manager as well as the
storage agents?
I was
errupt mitigation can usually
increase overall network throughput.
I wonder what throughput will be like on 10Gbit ethernet?

Is it the tracing causing the high system utilisation?
Ensure the application is allowed under the Windows execution prevention
tab- this can cause issues with java based applications.

vhost.exe eating 99%
It's all run from the command-line.. so java shouldn't be involved
Waiting for reboot..

Is it %util, or %migr that is 100%?
If caching is on, % util will always be high around 100% and the %
migratable is the actual utilisation by unmigrated data.

Are the disk volumes that make up this storage pool all online and
accessible?
What utilisation do they show?
