HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

• Mount point—The command changes the persistent mount associated with the filesystem on the
specified servers.
• The purpose of this command is not to have a filesystem mounted at a different mountpoint on
different servers. It allows an administrator to change the mountpoint on all servers OR change
the mountpoint on a subset of servers, mounting the filesystem with the new mount point on
only those servers and leaving the filesystem unmounted on the remaining servers.
• To change the mountpoint on one server only, use the modify filesystem command as
shown in the following example. (Note that you must use the server name, not the server
number):
# exdsmgr modify filesystem device=psv5 mountpoint=/usr/newdata
server=glory5
• To change the mountpoint on all servers, use the modify filesystem command as shown
in the following example:
# exdsmgr modify filesystem device=psv5 mountpoint=/usr/newdata
server=all
For more information about PSFS quotas, see the HP Polyserve Matrix Server 3.5 administration guide.
Managing NFS exports
The Matrix software manages NFS exports using an export group called exds_expg_default.
Unless otherwise specified, all exdsmgr commands operate on the exds_expg_default export
group.
Creating a VNFS configuration
The exdsmgr create vnfs command creates exds_expg_default export group with a default
balanced set of virtual host IP addresses. The export group will comprise all of the PSFS filesystems
that are currently mounted on the HP ExDS9100 system.
Parameters
• network=eth<number> (must not be the management network)
• Mandatory parameter. This network must have been configured by the exdsmgr reconfig-
ure system command. If you manually configure the network interface, use the mx or mx-
console commands to configure NFS on this network.
• vips=<a1.b1.c1.d1 | a2.b2.c2.d2, a3.b3.c3.d3, ...>
• Mandatory parameter
• Either a single VIP can be supplied or a comma-separated list of VIPs can be supplied. If a
single VIP is supplied, it is assumed to be the start of a contiguous list and the code constructs
a list with a length of the number of servers in the system starting with this value. If a comma-
separated list of VIPs is supplied, then the length of the list must not be longer than the number
of servers in the system.
• options=”<optionstring> [<optionstring> <optionstring>...]”
• <optionstring> has the syntax: <clients>(<exportoptions>), where
• <clients> specifies the allowed clients. The specification can be one of the following:
• * (for example, all clients)
• A Netmask (for example, 10.10.10.0/24 or 10.10.10.0-255.255.255.0)
