Chapter 7 HPSS User Interface Configuration
HPSS Installation Guide September 2002 457
Release 4.5, Revision 2
Gatewayspecifies the fully qualified name of the host where the DMAP Gateway that will manage
thisfileset runs. To keep the example above short, Gateway is shown as tardis, but in practice, the
name should be tardis.ca.sandia.gov. If the fileset is partially configured, the host name is
represented by a ‘?’. That prevents end users from accessing the DFS fileset. To complete the
configuration, an administrator will use SSM to create the HPSS fileset.
Port specifies the TCP port that the DMAP Gateway uses to listen for requests from HDM.
Conventionally,this is 7001. Do not confuse this port number with the port number used by HDM
tolisten for requests from the DMAP Gateway (6002). Until the fileset is fully configured, Port will
be shown as zero.
When multiple HDM Servers and DMAP Gateways are running, they must use different TCP
ports.
Following is a description of the parameters for an XFS filesystem:
Namespecifies the name of the filesystem. This is user-defined and should be descriptive.
Mediaspecifies the device for the aggregate in the form of <adapter>(<major>,<minor>). To
determine the media descriptor for your filesystem, you will need to follow these steps:
1. Findthe <major> and <minor> numbers for the disk partition containingyour filesystem
bylooking at a long listing of the /dev directory. For example, if your filesystem is on parti-
tion/dev/hdb7, do the following:
% ls -l /dev/hdb7
brw-rw---- 1 root disk 3, 71 Mar 23 2001 /dev/hdb7
The listing shows that the major number is 3 and the minor number is 71.
2. Next, determine the <adapter> that your partition is managed through. Use the major
number to lookup the appropriate block device in the/proc/devices file. Here is an
example:
% cat /proc/devices
Character devices:
1 mem
2 pty
3 ttyp
4 ttyS
5 cua
7 vcs
