Figure 2 Overview of the Audit Log Operations
You can transfer audit log to FTP servers or syslog servers after you connect these servers to the SVP of the
XP USP subsystem through LAN. You can connect up to two FTP servers and two syslog servers. The first
one is named primary FTP server or primary syslog server, and the second one is named secondary
FTP server or secondary syslog server.
The audit log is stored in the SVP and old data in the audit log is deleted when the number of lines of the
saved data in the file reaches the maximum number. If you configure the settings of the server such as IP
address, the audit log is transferred to the FTP server when the number of lines reaches the threshold, and
the audit log is always transferred to the syslog server.
To transfer the audit log to servers, you need to configure the settings of the server using the Syslog panel
or the Audit Log panel. Please refer to the Audit Log Reference Guide for the operation procedure
in each panels.
Important Terms and Concepts
XP Remote Web Console users should be familiar with the following terms and concepts:
•
Disk controller frame. The arrays have one disk controller frame that controls all data access
and storage operations. Mainframe environments provide up to 255 logical control unit (CU)
images and support 3990-6, 3990-6E, 2105-F20, and and 2107 controller emulation types.
Open systems provide up to 64 CU images.
NOTE:
The 3990-3 and 2105-E20 controller emulation types are not supported.
•
Disk array frame. The disk array frame for the XP arrays contains the storage components (hard
disk drive arrays).
•
Parity group. A parity group (also called an array group) is a set of hard disk drives that are
treated as one group. For example, a RAID-5 3D+1P parity group consists of four disk drives (3
data and 1 parity). A parity group contains both user data and parity information. The parity
information is used to automatically reconstruct the user data if one of the disk drives in the
parity group becomes unavailable.
