Re: ADSM/HSM migration candidates list
How quickly does dsmreconcile run and do you already have files in migrated
storage?

Apparently the policyset that this system was attempting to migrate to didn't have a Space Management Technique enabled. While the Standard policyset in this management class was set to Auto, the one specified in the include_exclude file was set to None. I appreciate this help Richard, and the many other times in the past that you have helped others in this forum. If only I could return the favor.

Re: ADSM/HSM migration candidates list
>Matthew - Is the file system occupied by small files, under 4KB in size? No, it isn't. In fact it is occupied by a few quite large files, between 100-500 Meg. There are some lock files in the filesystem, which are around 4KB, but the majority of the files are larger. Richard, maybe you or someone else can answer this question for me. The way I understand the product to work, it will always generate a migration candidates list based on the Age and Size factor settings, even if your thresholds are set so that migration will not occur. The candidates list is just a list of files and their score, and doesn't indicate that migration is eminant. I have configured this product on quite a few other machines in the past, this one just seems to be giving me trouble.

ADSM/HSM migration candidates list
Folks,
I can't seem to get HSM to generate a candidates list and begin migrating
files on an AIX 4.3.2 system. The version of adsm.client.aix42.hsm is
3.1.20.8, one of the most recent ADSM packages. Anyway, the high migration
threshold is set below the percent used for the filesystem, Space Management
is active for the filesystem and we have backed the files up using the normal
ADSM b/a client(even though the MIGREQUIRESBACKUP parameter is set to NO.)
Here are some commands and their output:
{ root@client } # dsmreconcile -c /b32tmd/tmd3
Reconciling '/b32tmd/tmd3' file system:
Querying the ADSM server for a list of backed up files...
Received 11616 entries
Now traversing the file system...
Writing the new migration candidates list...
Note: unable to find any candidates in the file system.
ANS9250I File system '/b32tmd/tmd3' reconciliation completed.
{ root@client } # dsmmigquery -c /b32tmd/tmd3
Candidates for migration in file system /b32tmd/tmd3:
no file exists in the migration candidates list

Anybody have any ideas? I have spent quite a few hours now playing with this,
making changes and attempting to generate a candidates list, all to no avail.
Maybe I need another set of eyes. Thanks in advance.
