Emc Data Domain; Options For Cifs Shares - F5 ARX-VE Planning Manual

EMC Data Domain

ARX Site Planning Guide
The EMC Data Domain system has a particular CLI command designed to
support the ARX proxy user: cifs option set F5. This command accepts the
domain and username of any valid Windows account, defined externally on
your Windows Domain Controllers (DCs):
cifs option set F5 domain\username
where
domain is the Windows domain for the proxy-user name, as defined on
your DCs.
username is the name of an existing Windows user, also as defined on
your DCs.
Then, run the filesys restart command. This gives the Windows user
Backup Operator privileges on the Data Domain system. For example, the
following command sequence provides Backup Operator privileges to
"jqpublic" on the Data Domain system named "med-dd510:"
sysadmin@med‐dd510# cifs option set F5 medarch.org\jqpublic
sysadmin@med‐dd510# filesys restart

Options for CIFS Shares

By default, the EMC Data Domain system allows access to a small number
of CIFS clients with read-only access. However, an ARX volume facilitates
read/write access to the Data-Domain share by any of its CIFS clients; even
if CIFS clients access this share infrequently, there is typically a wide
variety of them. When you use the cifs share create command to create a
CIFS share, use the following options to prepare it for an ARX volume:
cifs share create share‐name path /backup/path clients *
browsing enabled writeable enabled
where
is the name of the Data Domain share, as seen by the ARX
share‐name
volume.
path is directory path, which is always a subdirectory of /backup.
clients * allows all CIFS clients to access the share.
browsing enabled allows the ARX software to perform some
necessary management functions.
writeable enabled
write to the share.
For example, the following Data Domain command shares the
"/backup/buusers" directory so that it can be used in an ARX-CIFS volume:
sysadmin@swic‐dd510# cifs share create BUUSERS path
/backup/buusers clients * browsing enabled writeable enabled
Manually Preparing the Back-End File Servers
