GLYPH<SM590000> Determine the distribution package for IBM Spectrum Archive EE that is required for your system. For more information, see 4.2.2, “Installing the IBM tape device driver” on page 51. 

GLYPH<SM590000> For IBM Spectrum Scale prerequisites, see 3.3, “Hardware and software setup” on page 41. 

## 4.2.1 Installing the host bus adapter and device driver 

This section describes how to install the HBA and its device driver for use with IBM Spectrum Archive EE. 

To install the HBA and its device driver, see the documentation that is provided by the HBA manufacturer. 

If the HBA attached to the tape library is an Emulex adapter, add the following line to the /etc/modprobe.d/lpfc.conf  file: 

options lpfc lpfc_sg_seg_cnt=256 

Then, restart the server system for the change to take effect. 

For more information about fixes and updates for your system’s software, hardware, and operating system, see this website: 

## 4.2.2 Installing the IBM tape device driver 

http://www.ibm.com/support/fixcentral 

This section describes how to install the IBM tape device driver for use with the integrated LTFS function and later on for the actual IBM Spectrum Archive EE. In our examples, we refer to a Red Hat-based Linux server system that we used for writing this book and creating the examples. Always check the IBM Fix Central website for the current version of the IBM tape device driver, as shown in the following steps. The drivers that were used during the time of the development of the book might have newer updates available. 

Before you install the IBM Linux tape device driver, ensure that the following tasks are completed: 

GLYPH<SM590000> The HBA and its device driver are installed. 

GLYPH<SM590000> The tape drive and HBA are connected. 

GLYPH<SM590000> The tape library is powered on. 

GLYPH<SM590000> The tape drives in the library are powered on. 

GLYPH<SM590000> The following tape library and tape drives are configured correctly: 

– A logical library was created and configured. 

– Tape drive and control path are assigned to the logical library. 

– Physical media is assigned to the logical library. 

GLYPH<SM590000> The Linux server for this installation is powered on.
