Hi all,
I am looking to find out what data is stored on my TSM servers for a
node which is defined as a server. Specifically to find out why/what
data is being stored for each server to the other one to amount to
approx. 3.8TB and 4.2TB respectively which is causing me a bit of a
headache as I am running out of space in my storagepools.
The setup (and where the figures above are taken from):-
2 TSM servers, TSM and TSM1 which are set up so that all the clients
which connect to each of them have their data replicated to the other
TSM server. The servers themselves are (obv) defined to each other for
the node replication to work. The only other use of this is to do
database backups to each other. The nodes themselves aren't replicated
between themselves (they are type=server). Both servers are running on
AIX 6.1 TL7 and the TSM version is 6.3.3.0.
So if I do the following command on TSM:-
select substr(node_name,1,20) as "Node
Name",cast(float(sum(physical_mb)) / 1024 as dec(8,2))as "Space in GB",
sum(num_files)as"Number of files" from occupancy where node_name like
'TSM1' group by node_name
It returns:-
Node Name Space in GB Number of files
--------------------- ------------ ----------------
TSM1 3855.94 59
Likewise the other way around on TSM1 produces:-
Node Name Space in GB Number of files
--------------------- ------------ ----------------
TSM 4221.42 44
So I am specifically wanting to find out why/what data is being stored
for each server for the other one to amount to approx. 3.8TB and 4.2TB
respectively.
The filespace information that is held for each of these servers is as
follows.
On TSM:-
tsm: TSM>q file tsm1 f=d
Node Name: TSM1
Filespace Name: ADSM.SERVER
Hexadecimal Filespace Name:
FSID: 1
Platform: AIX
Filespace Type: ADSM_FS
Is Filespace Unicode?: No

On TSM1:-

Node Name: TSM
Filespace Name: ADSM.SERVER
Hexadecimal Filespace Name:
FSID: 1
Platform: AIX
Filespace Type: ADSM_FS
Is Filespace Unicode?: No

Backup Replication Rule Name: DEFAULT

Archive Replication Rule Name: DEFAULT

Space Management Replication Rule Name: DEFAULT
Space Management Replication Rule State: Enabled
The database backup that occurs between the 2 servers use 4 streams each
time and are kept for 4 days (DB Backup Series Expiration Days: 4 Days
from q drmstatus), so in my mind there should only ever be 16 files on
each server from the other server, not the amount of files that are
being reported above.
My database sizes are:- TSM = 434Gb, TSM1 = 276Gb (as an aside, why
aren't these the same size as they are storing the same amount of data?)
Would someone be able to shed any light on this or let me know if I can
provide any more information.
Thanks in advance,
Regards,
Steve
