Subject: Re: DFHSM MIGRATE MYSTERY
Joel,
I did a manual BACKDS command of the dsn. Next I did a LISTCAT of the
dsn and it shows LBACKUP ---2010.328.0643. I did a HMIG dsn ML2 . I
did a LISTCAT again and it shows LBACKUP ---XXXX.XXX.XXXX
However when I do HLIST of the dsn it shows the backup 10/11/24
06:43:55
I am not sure why this is happening. I also noted that if I issue the
HMIG dsn ML2 the MANAGEMENT CLASS Migration Attributes is being ignored
even though I have specified
the following:
Primary Days Non-usage . : 3
Level 1 Days Date/Days . : 2
Command or Auto Migrate . : BOTH
As an earlier poster had mentioned that if a manual Migrate ML2 command
is issued to migrate the dsn, it overrides the Migration attributes.
This storage group is exempt from Auto Migrate but it does have Auto
Backup turned on. I noticed that the Auto Backup is working. The
dataset in question was not backed up because it was created after the
Auto Backup had run.

Did you display the LBACKUP date while the file was migrated? On z/OS
1.10 I only see the actual last Backup date displayed if the dataset is
on a primary volume. If on ML1 or ML2 neither ISMF no LISTC will
display the backup date.
Did you do a
"HMIG dsnamefilter"
(which is a request to migrate to ML1) or
"HMIG dsnamefilter ML2"?
If I try to migrate a dsn with an autobackup management class to ML2
and
there is no backup yet, it fails with "ARC1280I MIGRATION FAILED - DATA
SET IS IN NEED OF BACKUP". If I try to migrate the same dataset to ML1
("ML2" parm omitted), migration succeeds. I think this is because
DFHSM
can still do an autobackup from ML1. Or If I then attempt to force a
migrate from ML1 to ML2 with "HMIG dsname ML2" before there is a
backup,
I also get the ARC1280I failure.

Mike,
I took your advice and set the MANAGEMENT CLASS AUTO BACKUP=Y.
As a test I created a new dsn using the same HLQ's and Management
Class. I tried the MIGRATE command via batch (using wild cards) it
went to ML1 instead of ML2 which was NOT happening before I changed the
AUTO BACKUP from N to Y. I did a LISTCAT of the dsn but it shows
that no backup was done. Inspite of this the dsn was sent to ML1. Not
sure why
LBACKUP ---0000.000.0000
If I understand Joel's post correctly in which he says that
"Migration Attributes for primary and level 1 only apply to auto
migration" then the dsn should not have been sent to ML1 but directly
to ML2.
Any suggestions?

You can requre that a successful SMS backup before it allows the
dataset to be migrated.

When the batch job is executed all the dsns (these are all VSAM
dsns) are migrated ML2 - including those that were created this morning
before the migrate was done. According to the Migration Attributes
shouldn't those dsns which were created today& yesterday not be
migrated?
Could someone help me understand where else I should look.
Thanks in advance for your help.
