Your backup command is:
BACKUP NODE node-name virtual fs name MGMT=nnn MODE=FULL TOC=YES
I use 'TOC=P'. We have one file system where we cannot generate a TOC because
of the number of files. TOC=PREFERRED will prevent the backup from failing
when TOC creation fails.

Subject: Re: [ADSM-L] Planning for NDMP backup
Hi Michael
I believe the backups can be stored on either disk or tape, but i only ever use
tape. This is mainly due to the size of the backups, ours range between 1tb -
25tb. If on disk, that's a lot of disk!
For the server that ran the NDMP backups, we always had at least 2 drives
defined to the data movers. Other activities such as normal B/A backups took
place which required reclaim and migration tasks and had to share the drives
with the NDMP backups. If i only defined one drive to NDMP and the drive was
busy, the backup would fail. So at least 2, and 4 drives if the NAS filer had
the fibre to allow it. One problem i had: because of the size of the dumps, we
never had the time to make offsite copies of the tapes.
Right or wrong (and i know it's wrong), i had limited resources in terms of
drives and time.
Lot's of different things with NDMP backups. These are a brief summary of my
own notes.
Define a domain for the NAS backups:
define dom nas desc='NAS Domain'
define pol nas nasp
Now register a node:
reg node node-name password type=nas dom=nas
Obtain the IP address of the NAS filer:
(From the NAS filer)
ifconfig sm_vif
Note the IP address
Now define the datamover:
define datamover datamover-name type=nas hla=ip-address lla=port
userid=node-name password=password-of-NAS-filer dataf=netappdump (Note the
format must be netappdump)
(Note2: I kept the datamover-name the same as the filer-name - no point
confusing things and keeps it simple)
>From the filer:
storage show tape
Obtain the Alias name. Normally something like st0 and st1
Define the paths in TSM:
def path filer-name drive0 srct=datamover desttype=drive library=xxxx
device=rst0a def path filer-name drive0 srct=datamover desttype=drive
library=xxxx device=rst1a
(Note the device of rst0a and rst1a. This is the st0 and st1 taken from the
filer and you need to suffix with an add 'a')
q path
Source Name Source Type Destination Destination On-Line
Name Type
----------- ----------- ----------- ----------- -------
tsm-server SERVER AUTOLIB0 LIBRARY Yes
tsm-server SERVER DRIVE0 DRIVE Yes
tsm-server SERVER DRIVE1 DRIVE Yes
filer1 DATAMOVER DRIVE0 DRIVE Yes
filer1 DATAMOVER DRIVE1 DRIVE Yes
(So now i see the 'normal' tape drive paths, plus the file ones)
Define my devc:
define devclass NASCLASS devtype=nas library=xxxx mountretention=0
mountlimit=drives estcapacity=1600g (this was an LTO4 library)
And a stgpool:
def stgpool <stgpool-name> NASCLASS poolt=primary acc=readw col=no reuse=3
dataf=netappd maxscr=2000 (Note the devc was the tape devc i just created. You
can do this to disk, of course)
And the mgmtclass and copygroup:
DEF MGMT NAS STANDARD 1M SPACEMGTECH=NONE AUTOMIGNO=0 MIGREQUIRESBK=YES
MIGDEST=SPACEMGPOOL DESC="NAS MC"
DEF COPY NAS STANDARD 1M T=BACKUP DEST=stgpool-name FREQ=0 VERE=28 VERD=28
RETE=28 RETONLY=28 MODE=MODIFIED SER=DYNAMIC
And finally:
VALIDATE POL NAS NASP
ACTIVATE POL NAS NASP
I recommend you use a TOC (table of contents). See the admin guide or admin ref
about this
Set up a Virtual Filespce:
DEFINE VIRTUALFS <nodename> <virtual-fs-name> <fs-name> <path> namet=server
(Note: The fs-name and path must match that of the Netapp filer) (Note the
virtual-fs-name is what TSM server knows the filer storage area
as)
This will backup the filer:
BACKUP NODE node-name virtual fs name MGMT=nnn MODE=FULL TOC=YES
THE BACKUP RUNS AS A PROCESS (not as a session) SO CHECK THE PROCESS TO CONFIRM
THAT THE BACKUP HAS BEEN SUCCESSFUL!
Notes:
Q NODE will not show NAS nodes. Need to use Q NODE TYPE=NAS The Admin Guide
states that Reclamation and Migration are not supported for these storage pools
I am sure there may be better ways, perhaps dedupe etc, not sure. But this is
what i setup
Best of luck
