IBM HPSS 4.2. Setup Filesystems, 4.2.1. DB2 Filesystem

•Configure the Perl prerequisite software on HPSS nodes.

•Configure the SSH prerequisite software on the core HPSS server node (at a minimum) and

configure SSH to accept connections from IBM Houston. Include the Houston subnet IP

addresses 192.94.47 and 12.39.169 in the local firewall routing rules, as necessar y.

•Obtain the HPSS deployment tool package from your customer support representative and

install it on each HPSS node in /opt/hpss/tools/deploy. Run and become familiar with the

lsnode tool, which will be helpful in other steps.

To run lsnode and save the output to /var/hpss/stats/lsnode.out:

% mkdir -p /var/hpss/stats

% cd /opt/hpss/tools/deploy/bin

% lsnode > /var/hpss/stats/lsnode.out

•Obtain your HPSS Realm Id from IBM. This information will be needed when mkhpss is

used to configure HPSS. For an existing installation, this is the ID which was previously

referred to as the DCE Cell ID.

4.2. Setup Filesystems

The following sections describe how to set up the various filesystems used by HPSS and DB2.

4.2.1. DB2 Filesystem

Each database in DB2 has its own log. We recommend that these logs be placed on a filesystem

reserved exclusively for this purpose. This should be a fast, but more importantly, stable disk,

preferably a RAID device. For example, the following filesystems might be created for a

configuration database and subsystem database:

/db2/log/cfg

/db2/log/subsys1

The NEWLOGPATH database configuration variable can be used to direct the database logs to these

filesystems.

Additionally, the following filesystems are required for storing the mirrored copy of the DB2 logs:

/db2/mirror-log/cfg

/db2/mirror-log/subsys1

The DB2 log mirroring is configured using the MIRRORLOGPATH variable.

The home directory of the DB2 instance owner should be created as a separate fil e system on each

HPSS node that runs a database instance. By default, the DB2 instance owner is “hpssdb” and its

home directory is /var/hpss/hpssdb.

If the backup utilities included with HPSS will be used for backing up DB2, a filesystem should be

created to serve as the disk storage area where backup data is placed before being archive d to tape.

For example:

/db2/backups/cfg

/db2/backups/subsys1

/db2/backups/ldap

/db2/mirror-backups/cfg
