Messages will be provided to indicate the status of the HPSS infrastructure conﬁguration process

at each stage. The HPSS infrastructure conﬁguration results can be obtained from the messages

displayedduring the HPSS infrastructure conﬁguration process or can be reviewed by reading the

/opt/hpss/conﬁg/mkhpss.data ﬁle. Do not alter this ﬁle.

The hpss_unmake ﬁle contains information needed for the Unconﬁgure HPSS option. This ﬁle is

in the/opt/hpss/conﬁg directory. Do not alter this ﬁle.

Thesfs_servers ﬁle contains information needed for the Unconﬁgure Encina option. Each entry in

this ﬁle has a name and the disks used for each SFS server. This ﬁle is also in the/opt/hpss/conﬁg

directory. Do not alter this ﬁle.

Although it is recommended that themkhpss script be used only once per node to conﬁgure the

HPSSinfrastructure, it can be run again to correct or modify the infrastructure conﬁguration as

needed. However, after the HPSS servers are conﬁgured,mkhpss should not be used to modify

DCE, Encina, or any other data that may affect the conﬁguration of the HPSS system.

The following steps are automatically performed at the beginning of eachmkhpss execution:

1. Load in the environment variables deﬁned in thehpss_env ﬁle and hpss_env_defs.h ﬁle.

2. Verify that the user has root authority.

3. Create and initialize directories and ﬁles required for running HPSS.

4. Edit themkhpss.data ﬁle to record status messages and processed states.

Thisoption can only be performed from a node with the HPSS All Servers package installed. This

optionshould only be performed once in the cell. The System Administrator should propagate the

Customize DCE Keytabs Files on page 246 for more information. The following steps are

automatically performed:

1. Remove the HPSS keytab ﬁles, if any exist.

2. Create DCE groups for the HPSS servers and clients.
