1)
WHAT IS YOUR DAILY ACTIVITES?

Checking
DB backup status, if it is not completed for the day then we will take Manual
DB backup
3.
Troubleshooting
Missed/Failed Backpus based upon
Priority.

2)
TSM LICENCING?
·
Tsmbasic.lic
----for basic version
·
Tsmee.lic-----for
extended edition
·
Dataret.lic---for
data retention version
3)HOW
MANY TIMES YOU WILL TAKE DB BACKUP IN YOUR ORGANIZATION?
We Have a
Admin Schedule Where It will take Backup of DB Once in a day.
DEF SCHEDULE
DBBACKUP CMD=”BACKUP DB DEVC=FILEDEV1 TYPE=FULL” PERIOD=1 DURATION=24 DURUNITS=HOURS
ACTIVE=YES PRIORITY=1”
Ba Db
devc=devclassname t=full wait=no
4)
WHAT TYPES OF TAPES YOU ARE USING?
LTO1---100--------200---15Mbps
LTO2---200--------400---30
Mbps
LTO3---400--------800----80
Mbps
LTO4---800--------1600---120
Mbps
5)
How Can U Find What Type Of Tape U R Using?
Q libv
library nameàfor ex: LTO 3
6)
HOW CAN U DELETE THE DB BACKUP TAPES?
Delete
volhistory type=DB backup begind=-6
endd=-2
7)
HOW U CHECK THE FAILED AND MISSED BACKUP INFORMATION?
Q Event * *
Exception=yes+++
Q Event * *type=admin-------It display only admin schedules
8)
WHAT WE HAVE TO DO IF CLIENT BACKUP IS FAILED OR MISSED?
First take
the node name and query it in TSM Server by q
n nodename f=d, Here you wil find the ip address, then based upon the OS
login in to the client system, check
dsmerror.log and dsmsched.log
Based upon
the error trouble shoot it
9) HOW CAN WE
CHECK TSM SCHEDULAR IS RUNNING OR NOT IN UNIX?
Ps – ef | Grep
Dsmcsched
To start the services in UNIX Flavors
sudo /opt/tivoli/tsm/client/ba/bin/dsmc sched > /dev/null 2>&1
sudo nohup dsmc schedule 2 > /dev/null &
sudo /opt/tivoli/tsm/client/ba/bin/dsmc sched -quiet &
sudo dsmc -optfile=/opt/tivoli/tsm/client/ba/bin/dsm.opt
10)
HOW CAN U LOG IN TO THAT PARTICULAR NODE WITH OUT KNOWING THE IPADDRESS?
By Using the
cmd i.e Q NODE NODENAME F=D
It will
display the Tsm Name---Host name of the system
It will
display the Tsm address----Ipaddress of the system
Still if you
not able find the ip address, you will be having internal tool to check the
hostname and ipaddress.

2.
Directory path not found
3.
Invalid password
4.
TCP/IP issue
5.

6.
Incremental processing on file system stopped
16) Backup
Missed.

6.
Backup status:
Definations :
Successful: Successful backups are those where all files are backed up.
Ex 100 out of 100.
Partial: Partial backups are results of successful backups but not all
files are backed up. There will be a difference between processed files for
backup and actual backup.
Failed: Failed backups are those that are results of backup that are
unable to backup certain file or failed during backup.
Missed: Missed backups are those that did not start during the specified
duration window.
17) what is reclamation? Which tape
is eligible for reclamation?
reclamation
is the process of moving the un expired data from fragmented
tapes to another tapes which are in filling state. The tape that shows full state , but the pct
utilization low, then the tape is eligiligible for reclamation based on the
reclamation threshold.
18) RETURN CODES AFTER SCHEDULING?
0---àOperation
completed successfully

completed successfully except with one or more skipped files
8---à operation
completed with one or more warning message object
12--àOperation
failed with one or more error messages
19) EVENT MESSAGE FORMATING?
AN[R S E]
------------àR---Server-------
S---Client E---Event
àI
Information, W Warning, E-Error, S Severe
20) TO CHECK THE SERVER INSTALLATION HAS
COMPLETED SUCCESSFULLY?
Windows------INITSERV.LOG
21) PASSWORDACCESS GENERATE?
Tsm client
password is encrypted and stores in a file on the client. If a client receives
that password
Has expired
from the tsm server then client generates a new password
NOTE: password dir is a option in the b/a
client to specify the location of the encrypted password file
But win32
systems are having exception that the encrypted password stores in the registry
22) TIPS & HINTS FOR LIBRARIES, DRIVES AND
DEVICE DRIVERS PROBLEMS?
1.
Has
the o/s changed
2.
Has
the host bus adaptor Or scsi adapter connecting to the device updated or
replaced
3.
Has
the adopter firmware changed
4.
Has
the cabling between the computer and device changed
5.
Are
any of the cable connections loose
6. Has a device
driver changed
23) when the drive is offline the
what u will do?
try to make
it online using update drive command
Update drive
libraryname drivename online=yes.
Still it’s
not coming to online then do power cycling means power on/off.
I have mentioned some of the issues I have
faced in my environment. I hope this will be little useful...
1. Drive was
in unavailable state
The drive was
not in online. means we are not able to access the drive.
Action
followed:
> We make
the Drive to offline from TSM server.
> We
recycled the drive (Power Off and ON)
> Did a
cleaning for that drive.
> Then
Drive was working but the library was still showing the error message in the
log.
> Then we
rebooted the Library once to delete the error log message the inventory
24) what situations migration will
fail?

26) what is the library model u r using?
3584 , type
scsi
27) how to define a library?
define libray
libraryname librarytype
shared=yes/no
Search=no
means server check in the named volumes
Yes: server
searches the library for volumes that are to be checked in.
Bulk: server
searches for the library I/o ports that
are checked automatically.
28) how can u do the migration manually ?
migrate stg
stgname lowmig=%
Update stg
stgname nextstg=stgname

server?
fist define
stg
Def policy
set
Def mgmt
class
Define copy
group
Register the
node in tsm server and assign that node to domain.
33) how to configure the ba/ client?
in dsm .opt we have to configer
server ip address
Communication method,tcpipport,node name ,password access generate.
34) how to check in library?
checkin
libvol libraryname volume name
search=no/yes /bulk status=private/scratch
checklabel=yes
35) how to checkout from library?
checkout
libvol libraryname volumename
remove=yes/no/bulk.

36) how to define device class?
define deviceclass deviceclassname
devicetype=file directory=
path maxcapacity= ..mb(if it is a file device class)
37) what will u do when recovery log
utilization reaches to high?
if there is
any space available then extend the log size
then take the db backup
If the space
is not available then go for show logpin for which session is pinning the
recoverylog,
And cancel
that session using cancel session
session no.
38) what is
pinning ?
Which session
increases the recovery log utilization .
39) how to take the backup of

u do when the library is full ?
first
check all the DR volumes are checked out
from the library or not
Using q drmedia
* where state=mountable.
Check out all
the primary storage tapes to make room empty for scratch tapes.
Verify that all volumes have space to be reclaimed
Are reclaimed
and use move data command to move the data manually.
It’s the time
to buy a new library.
49) what will u do when the drives
are offline?
when the
drives are offline then update the drive and drive path
Update
