Make sure your system and storage solution meets the requirements in this section.
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.
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 23.4: 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.
For information about installing and using the storage-related iManager plug-ins, see Section 10.1, iManager and Storage-Related Plug-Ins.
