4.Review and update the Core Server(s) other configuration parameters, if necessary

5.For 4.5 upgrades only: Review all migration policies to ensure that they were converted correctly

In pre-5.1 HPSS systems, migration policies could apply to both a disk and tape storage class. In HPSS 5.1, the migration policies were modified to apply only to disk or to tape, but not both. The conversion utility examines each migration policy and attempts to determine whether the policy was intended to be used by a disk or a tape storage class. If the policy is in use by both a disk and tape storage class, the program will produce a new but identical migration policy and classify one of the policies as type disk and the other as type tape, then update the appropriate storage class to use the correct migration policy. Benign warnings from the db_convert_mps utility may be observed indicating that a given migration policy id has both disk and tape flags set. In this case, the program will leave both flags set but output this warning. To correct, the incorrect flag should be unset using SSM. Additionally, the program may also warn when a migration policy is not in use by any storage class. In this case, the program will designate this migration policy as disk and leave it unassigned.

6.3.20.3. Dump Accounting Metadata, if applicable

At this point, the accounting metadata has been converted. For a single-subsystem HPSS, that conversion is sufficient. For a multiple-subsystem HPSS, perform the following steps:

1.For each subsystem database, empty the acctsum, acctlog, and acctsnap tables. This is accomplished by using the following commands:

db2	connect to	<db>	(e.g., "db2 connect to subsys1")
db2	set schema	hpss

db2 delete from acctsum db2 delete from acctlog db2 delete from acctsnap

Note that this is done once for each subsystem and that <db> is replaced by the name of the subsystem database.

2.Swap the accounting bits for each Core Server.

There are two accounting bits for each bitfile. One bit is active at a time; the Core Server's specific configuration indicates which bit is currently active.

For each Core Server, use the load_core_config utility located in the tools/load directory and update the specific configuration to use the other bit (the one not currently being used). This is done by invoking load_core_config and selecting the proper subsystem. The configuration
