Configuring a Namespace

Setting the Namespace Protocol(s)

7-10 CLI Storage-Management Guide

For example, this command set allows two forms of NFS access to the “wwmed”

namespace:

bstnA6k(gbl)# namespace wwmed

bstnA6k(gbl-ns[wwmed])# protocol nfs2

bstnA6k(gbl-ns[wwmed])# protocol nfs3

bstnA6k(gbl-ns[wwmed])# ...

Removing a Protocol

Use the no form of the protocol command to remove a protocol from the namespace.

no protocol {nfs2 | nfs3 | nfs3tcp | cifs}

where you must choose one of the flags, nfs2, nfs3 (over UDP), nfs3tcp (NFSv3

over TCP) or cifs.

For example, this command set removes NFSv2 from the “wwmed” namespace:

bstnA6k(gbl)# namespace wwmed

bstnA6k(gbl-ns[wwmed])# no protocol nfs2

bstnA6k(gbl-ns[wwmed])# ...

Creating a Multi-Protocol (NFS and CIFS) Namespace

If all the back-end shares support both NFS and CIFS, you can configure a

multi-protocol namespace. Clients can access the same files from either a CIFS or an

NFS client.

The namespace can be backed by a heterogeneous mix of multi-protocol filers,

possibly from multiple vendors. The switch passes client requests to these filers, and

passes filer responses back to the clients. File attributes, such as file ownership and

permission settings, are managed by each filer. Each filer also manages its file and

directory naming; if a name is legal in NFS but illegal in CIFS, each filer creates a

filer-generated name (FGN) for its CIFS clients. Different vendors use different

conventions for attribute conversions and FGNs, so that a CIFS-side name and/or

ACLs at one filer may be different at another filer.

These issues are important to managed-volume configuration, and are discussed at

length in the managed-volume chapter (as well as the CLI Maintenance Guide).
