TSM Server DB and Log size monitoring, client and admin schedule monitoring, and library media management. I also have to install and configure TSM BA clients whenever required and troubleshoot backup/restore issues if any.
First * is Domain name, the second * is schedule name
Query Event * t=a
1. We can check it in actlog for hardware/media & read-write errors by using the command – “q actlog se=errors”
2. To determine read/write errors for a particular volume run the command “q volume f=d“.
This output will show the number of reading/write errors that occurred to that particular volume.
Approximately 60 GB.
Tip: size depends on your environment
HP LTO4 tape – capacity 800 GB, speed is 120 MB/Sec.
Yes, In our environment we should do DR drills every 6 months to ensure we are ready for any disaster recovery.
Yes, I did it once.
IBM 3584 library model with 4 drives
STEPS TO INSTALL AND CONFIG TDPSQL
The maximum parameter is used to increase/decrease the client backup/restore sessions. This parameter value should not be greater than available tape drives.
Collocation is the process of keeping the client-backed up data in a minimum number of tapes. Collocation can be done by nodes, node groups, and by Filespace. We will update collocation while defining or updating storage pool definitions.
update stgpool colloc=node
Cloptset is used to define a name for a set of options that you can assign to clients for archive, backup, restore, and retrieve operations. We should first define a clioptset name by using the “define cloptset” command and then define each client option to that cloptset by using the “define clientopt” command.
Then you should use this cloptset name while defining any client node. Generally, cloptset is used to assign extra client options for any particular node from the TSM Server end without logging into the client machine.
To determine read/write errors for a particular volume run “q volume f=d“. This output will show the number of reading/write errors that occurred to that particular volume.
First, we have to figure out the source of the error, whether the tape drive has caused the error, or the tape itself has some problems. If the tape drive is the culprit make sure no other tapes are mounted on that particular tape. If the tape itself has problems, then audit that tape by using the “audit volume fix=no” command.
This will show if there are any damaged files. IF there are no damaged files move the data from that tape to another tape, if there are any damaged files then we should restore the contents of that tape from the copy storage pool.
Yes, We can do it by the BA client command line and also through the BA client GUI.
Yes, I have client login credentials with limited privileges.
3 TSM Servers
TSM LIBRARY MANAGER
We have to define all the drives on both the Library Manager and Library clients. CONFIGURATION OF TSM LIBRARY MANAGER
By running “storageagentname:q session”
Querying act log for “ANR0415I” message which says that “session 101 was proxies by storage agent S1 for node N1”
You can also check the backup report for the total lanfree bytes transferred.
Generally, the tape library will have separate cleaning drives, we have to just mount that drive through Library GUI. OR From TSM Server we can run the “clean drive” command, this will also mount the cleaning cartridge/tape onto the drive and starts cleaning.
If new tapes are kept in the I/O exit port, run the below command
label libvol search=bulk labelsource=barcode checkin=scratch
TROUBLESHOOTING TAPE LIBRARY
a version exists, version deleted, retention extra, retention only, serialization, destination, mode, frequency …… etc.
Reclamation makes the fragmented space on volumes usable again by moving any remaining files from one volume to another volume. This action makes the original volume available for reuse.
No, reclamation will move both active and inactive data.
Audit volume command is used to check the inconsistencies between database information and a storage pool volume.
Fix - Specifies how the server resolves inconsistencies between the database inventory and the specified storage pool volume.
Fix=No - Tivoli Storage Manager reports, but does not delete, database records.
Fix=Yes - The server fixes any inconsistencies as they are detected
Migration is used to move client files from one storage pool to the next storage pool in the storage hierarchy. The migration will make some empty space in disk pools which can be used for taking a backup of the client machine.
Yes, we used the Same System Media Method
Yes, First we have to copy all the important client configuration files, disconnect the connection with TSM Server and then uninstall/install the new client version.
TSM SERVER 6.3 INSTALLATION STEPS
RECOVERY LOG IN TSM VERSION 6.30
dsmsched.log & dsmerror.log will contain the client schedule status details and any schedule error details.
No, Lanfree data will go directly to tape/tape pools. If we have a disk library in a SAN, then we can send lanfree to disks but we need another supporting software.
Query db f=d
query path f=d
update path source name destination name srctype=server desttype=drive/library device=devicename online=yes
YES – Specifies that the server labels only volumes that are stored in the library
BULK – Specifies that the server searches the library entry/exit ports for usable volumes to label
It contains all the tdpsql performance monitoring parameters like Buffers, Buffers size, SQL buffers, SQL buffer size, data stripes, and log files, etc.
INSTALL AND CONFIGURATION OF IBM TDPSQL
OFFSITE RECLAMATION PROCESS
If there are any read/write errors on the primary pool volumes, we can restore them from copy pool volumes.
STEPS TO INSTALL AND CONFIGURE TSM STORAGE AGENT
TSM POLICY MANAGEMENT BASICS & POLICY STRUCTURE
a version exists, version deleted, retention extra, retention only, serialization, destination, mode, frequency …… etc
It specifies how Tivoli Storage Manager processes files or directories when they are modified during backup processing.
