The devclass option is there to specify what sort of device you want the backup to goto. In our environment for example we have an IBM 3494 library so I state devclass: "3590dev" and it directs my backup to media belonging to that devclass. Below is the a procedure I typed up for backing it up to a file:
This procedure details how to backup a TSM database to a file on the system rather then a tape. First pick a directory which lies on a file system which has enough disk space which exceeds the current database utilization limit so you know you have enough room. You do that by entering this command (EX: /usr): # df -k /usr <ENTER> Filesystem 1024-blocks Free %Used Iused %Iused Mounted on /dev/hd2 4096000 2585352 37% 22432 3% /usr # Now you have determined that the "/usr" filesystem has enough room for a "2" gig database. Now login to TSM as the admin (dsmadmc). Once in you must create a file device class, you do that by entering the following: > define devclass diskdbbackups devtype=file directory=/usr/dbbackups/ <ENTER> To verify that device class now exists, type in the following: > q devclass <ENTER> Device Device Storage Device Format Est/Max Mount Class Access Pool Type Capacity Limit Name Strategy Count (MB) --------- ---------- ------- --------- ------ -------- ------ DISK Random 3 diskdbbackups Sequential 0 FILE DRIVE 4.0 1 NULL Sequential 1 FILE DRIVE 3,000.0 256 As you can see from the output above it does now exist. Now to perform the backup to disk type in the following: > backup db devclass=diskdbbackups type=full volumename=/usr/dbbackups/todaysbackup <ENTER> ANR2280I Full database backup started as process 1. ANS8003I Process number 1 started. To check the progress of this database backup type in the following: > q pro <ENTER> Process Process Description Status Number -------- -------------------- ------------------------------------------------- 1 Database Backup Full backup: 192 pages of 219 backed up. Current output volume: /usr/tivoli/tsm/server/bin/dbbac- kup. --Justin Alexander Lazarevich To: [EMAIL PROTECTED] <[EMAIL PROTECTED] cc: G.UIUC.EDU> Subject: backup database Sent by: "ADSM: Dist Stor Manager" <[EMAIL PROTECTED] .EDU> 10/27/2002 09:09 PM Please respond to "ADSM: Dist Stor Manager" we've got adsmserv 3.1 running on an AIX 4.3.3 system, with a IBM 3575 library. i need to backup the database, but i dont understand how to do it exactly. ive read the manual but it sucks. okay so the command is adsm>backup db devclass=file type=full i need to do a full because ive never backed up the database before. but i dont understand the devclass option. do i just type in a path to the file that i want the backup to be? for example, if i want to backlup the datebase to a file in /home/servercrap/adsmstuff/DBbackup, then i just do this command: adsm>backup db devclass=/home/servercrap/adsmstuff/DBbackup type full if that directory already exsists, will the above command will do it? thanks in advance! alex --- --- Alex Lazarevich | Systems | Imaging Technology Group [EMAIL PROTECTED] | (217)244-1565 | www.itg.uiuc.edu --- ---
