HP XC System Software Administration Guide Version 2.1

options
Specifies a comma-separated list of options, as
defined in the
csys
(5) manpage.
The hostaddress and _netdev options are mandatory.
•Thehostaddress argument specifies the node that serves
the file system to other nodes and specifies the network
(administration or system interconnect) to be used. The
hostaddress is specified either by its node name or by
its IP address.
The following entry uses the nod e name for n60 over the
administration n etwork.
hostaddr=n60
The prefix ic- specifies the system interconnect. The following
entry uses the node name for n60 over the system intercon nect.
hostaddr=ic-n60
The following entry uses the IP address for n60 over the
administration network, 172.22.0.6 0. The second octet, 20,
specifies the administration network.
hostaddr=172.20.0.60
The fo llowing entry also uses th e IP address f or n60 over
the system interconnect. The second octet, 22, specifies the
system interconnect.
hostaddr=172.22.0.60
•The_netdev argument informs the system startup scripts that
this fi le system should not be mounted until th e network is up.
These parameters are interpreted differently depending on whether the host is e xporting or
importing the file system:
• The export ing host, which is sp ecifi ed with the hostaddr parameter, moun ts the file
system lo cally and exports it to the other nodes.
• The nodes whose host name do es not match the hostaddr parameter import the file
system.
An example entry follows:
/dev/sdb1 /scratch csys hostaddr=n60,_netdev
The node n60 mountsthefilesystem(whosedevicenameis/dev/sdb1)as/scratch
locally, and automatically exports it over the administration network.
14.3.2 Mounting Internal File Systems
Use th e following procedure t o mount a file s ystem on a disk on o ne node in an HP XC system
to o ne or more other nod es:
1. Log in as superuser on the head node.
2. Determine which file systems are to be mounted and from which node they are to be
exported.
The /proc/partitions file displays the partition s and their device names. Execute
the mount command to determine w hich of these partitions are already mounted.
In the example, node n60 mounts the f ile system who se device n a me is /dev/sdb1
locally as /scratch an d exports the file system. Nodes n61, n62,andn63 import
thefilesystem.
