• Logging
•
Server stores a number of consecutive invalid sign-on attempts by node
or administrator.
• Lock out
•
Storage administrator may set number of failed attempts before lock-out.
– SET INVALIDPWLIMIT
• Unlocking
•
Once administrator or node is locked out, authorized administrator must
unlock.
– UNLOCK NODE
– UNLOCK ADMIN
20
Password Security
• Customizable password restrictions
•
Administrator may set system-wide minimum password length.
• New command
– SET MINPWLENGTH
• Force password reset
•
Administrator may force client or administrator to change password at
next login.
– FORCEPWRESET=YES|NO
– UPDATE NODE or UPDATE ADMIN
– REGISTER NODE or REGISTER ADMIN
• Password expiration
•
SET PASSEXP days
• Can be set to zero (no expiration)
• Can be set on a per ID basis

Move Data by Node
The MOVE NODEDATA operation may appear to be incomplete
for a number of reasons. And example of one way:
1. The move node data operation is started
MOVE NODEDATA bob FROMSTG=stgpoola
TOSTG=stgpoolb
2. The following MOVE DATA is started
MOVE DATA vol3 STGPOOL=stgpoola
At the start, the move node operation determines that the
VOL1, VOL2 and VOL3 are volumes that have data for node
BOB and queues those volumes onto a list to process.
However, by the time the move node data operation actually
starts to process VOL3, all of BOB’s data in VOL3 may have
been moved to another volume, due to the MOVE DATA
operation, and thus would not be available for the MOVE
NODEDATA operation.

• Tape Devices
• Terminology
• How Storage Manager Uses Sequential Access Devices
• Process for Configuring a Tape Library
82
Tape Devices
• IBM Tivoli Storage Manager supports more than 300 tape
and optical devices.
• Check the supported device list.
• Tape devices are referred to as sequential access devices.
www.tivoli.com/support/storage_mgr/tivolimain.html
83
Terminology
• Library
•
A device that organizes and holds one or more tape drives, one or more
tape volumes, and an optional robotic mechanism.
• Drive
•
A hardware device capable of performing operations on a specific type of
sequential media.
• Device Class
•
Represents a device type which defines the tape media used in the library.

• Tape volumes are assigned or owned among the servers using
library manager categories. This is true for 3490 tape library.

Synchronous Administrative Commands
• Synchronous Processing
•
Allows Storage Manager to run in the foreground.
• Implemented with the WAIT option on commands.
Ignored from server console.
tsm> backup stgpool backuppool copypool wait=yes
• Enhanced Process Tracking
•
Enhanced return codes from processes.
• Additional process completion message.
– Explicitly issued to report results of process.
– Reports successful completion or reports an error code.
•
Results of background processes logged in activity log as before.
