4.1 Requirements for Installing NSS

4.1.1 Device Requirements

The following requirements apply to devices for NSS on the latest release of OES:

  • NSS can utilize device sizes up to 2E64 sectors (that is, up to 8388608 petabytes (PB) based on the 512-byte sector size) with a maximum pool size of 8 TB for NSS32 pool and 8 EB for NSS64 pool. For information, see Section 11.1.1, Device Size.

  • At least 12 MB of free space is needed on the storage media for each NSS pool you plan to create.

  • At least 12 MB of free space is needed on the storage media for each software RAID segment you plan to create.

  • For information about devices to use in a virtual environment, see Section 7.0, Using NSS in a Virtualization Environment.

4.1.2 Requirements for NSS

General Requirements

The following general requirements apply to NSS:

  • A physical server or virtual server running OES.

  • NSS is not installed by default. You can select it during the YaST install, or install it at any time from the YaST > Open Enterprise Server > OES Install and Configuration.

    For information about install options, see Section 4.2, Installing and Configuring NSS.

  • The NSS file system is used only for data volumes on OES. The Linux operating system requires a Linux POSIX file system for its system volume, such as Ext3.

  • After installing OES, install only approved updates. Refer to the OES 2018 SP3: Installation Guide to install the approved updates.

  • A NetIQ eDirectory Read/Write replica must be available in the same tree as the server when you create an NSS pool or volume so that the Storage objects can be created in eDirectory; otherwise, NCP cannot map to the pool or volume.
