Sun QFS and Storage Archive Manager (SAM): sam-amld Daemon Becomes Unresponsive And Has init As a Parent (Doc ID 1908038.1)

Last updated on SEPTEMBER 20, 2019

Applies to:

Oracle Hierarchical Storage Manager (HSM) and StorageTek QFS Software - Version 5.3 and later
Information in this document applies to any platform.


When stopping the samfs archiving daemons by running a samd stop, the sam-amld(1M) daemon does not get killed and it's parent becomes the init(1M) process.

# /bin/ps -edalf

0 S     root 17025     1   0  40 20        ?   1281        ?   May 19 ?           0:02 sam-amld

0 Z     root 17041 17025   0   0  -        -      0        -        - ?           0:01 <defunct>

In the above output, there are also 3 <defunct> processes, each with the parent process ID pointing to the runaway sam-amld(1M). These defunct processes correspond to its childprocesses sam-catserverd(1M), sam-scannerd(1M) and sam-robotsd(1M) respectively.

As a result, the archiving daemons can not he restarted, as a (rogue) sam-amld(1) is already running, and the sam-fsd(1) master daemon verifies that only 1 sam-amld(1M) process is running at any time.


 Customer changed the partitioning of the robot without first logically offline the library and drives in samfs.
