Using a SAN with Tivoli Storage Manager allows the following functions:
The following tasks are required for Tivoli Storage Manager servers to share library devices over a SAN:
Before Tivoli Storage Manager servers can share a storage device over a SAN, you must set up server communications. This requires configuring each server for Enterprise Administration and defining the servers to each other, using the cross-define function. See Setting Up Communications Among Servers for details. For a discussion regarding the interaction between library clients and the library manager in processing Tivoli Storage Manager operations, see Performing Operations with Shared Libraries.
You must first set up the device on the server system. This involves the following tasks:
Use the following procedure as an example of how to set up a Tivoli Storage Manager server as a library manager. The server is named ASTRO:
define library sangroup libtype=scsi shared=yes
define path astro sangroup srctype=server desttype=library device=/dev/lb3
For more information about paths, see Defining Paths.
define drive sangroup drivea element=16 define drive sangroup driveb element=17
define path astro drivea srctype=server desttype=drive library=sangroup device=/dev/rmt4 define path astro driveb srctype=server desttype=drive library=sangroup device=/dev/rmt5
For more information about paths, see Defining Paths.
define devclass tape library=sangroup devtype=3570 mountretention=2 mountwait=15
checkin libvolume sangroup search=yes status=scratch checklabel=barcode
label libvolume sangroup search=yes labelsource=barcode checkin=scratch
define stgpool backtape tape maxscratch=50
Use the following sample procedure for each Tivoli Storage Manager server that will be a library client server.
define server astro serverpassword=secret hladdress=9.115.3.45 lladdress=1580 crossdefine=yes
define library sangroup libtype=shared primarylibmanager=astro
define drive sangroup drivea define drive sangroup driveb
define path judy drivea srctype=server desttype=drive library=sangroup device=/dev/rmt4 define path judy driveb srctype=server desttype=drive library=sangroup device=/dev/rmt5
For more information about paths, see Defining Paths.
define devclass tape library=sangroup devtype=3570 mountretention=2 mountwait=10
define stgpool backtape tape maxscratch=50
After you have attached and defined your devices, you can store client data in two ways:
