NAS

Overview

This function displays a list of shared folders that are used in a NAS environment.

This function is displayed in a Unified Storage environment.

Caution

  • This function is not supported for the ETERNUS DX60 S5, the ETERNUS DX900 S5, the ETERNUS DX8100 S4/DX8900 S4, and the ETERNUS AF150 S3/AF250 S3/AF650 S3.

  • When attempting to display the list of shard folders while a meta cache redistribution is being performed for NAS volumes (NAS user volumes or NAS backup volumes), the process may be delayed for a maximum of two minutes.

Note

  • A unified upgrade is necessary for a storage system that will be used in a Unified Storage environment if it was previously used in a SAN environment. Refer to the [Register Unified Storage License] function and the [Apply Controller Firmware] function for details. This function is added in the category after the unified upgrade is complete.

  • Shared folders include home directories.

    "Home directory" is created for each user and is used as a dedicated shared folder that can be used freely by the user. Users that are authenticated by the Active Directory authentication server or the local user authentication use home directories with a CIFS connection.

    User name or group name [Type, Authority]

    • Type

      This item shows whether the displayed name is for user or group (u: User, g: Group).

    • Authority

      This item shows the access permission (r: Read Only, rw: Read/Write) for the displayed name.

      • "Read/Write" indicates that reading from and writing to the shared folder is allowed.

      • "Read Only" indicates that the shared folder is read only.

  • If "Everyone" is displayed as the group name, the specified authority is applied to all users and groups. In this case, "Type" is omitted.

[Example]

aaa000 [u, rw] (Type is "User", name is "aaa000", and authority is "Read/Write")

group0 [g, r] (Type is "Group", name is "group0", and authority is "Read Only")

Everyone [rw] (Type is "Everyone" and authority is "Read/Write")

Note

  • User and group are user information that is managed in the Active Directory authentication server.
