1 Overview This chapter describes the Logical VGA SnapShot overview. Version information before start Overview of the Logical VGA Snapshot Overview 1-1
Version information before start LP Web System may display different contents depending on the logical partitioning manager firmware version. So, this document uses "LP Web System" for the explanation of screen and operations hereafter. If your system shows HVM Logical VGA SnapShot Web System, read the following explanations of "the LP Web System" with it. 1-2 Overview
Overview of the Logical VGA SnapShot LPAR manager provides Logical VGA SnapShot, which can view or acquire the images that a guest OS running on each logical partition has output on the display unit. With this function, the images output on the display unit by each LPAR (logical partition) can be acquired as snapshots (still images) at any time. To do this, the Web browser on an external console will access the Web server to acquire the snapshot images provided by the LPAR manager. Telecommunication over http can be disabled by one of the HVM Management Commands, namely one of the HvmSh commands. (Note that rebooting the target LPAR manager is necessary to disable telecommunication over http.) For the detail, see HVM Management Command (HvmSh) Operation Guide. (1) Logical VGA SnapShot Configuration Diagram The following figure shows the Logical VGA SnapShot configuration. LPAR manager LPAR1 Guest OS (c) External console Web browser image acquisition request image display (b) snapshot image acquisition Web server image acquisition (a) virtual VGA device : : : LPARn Guest OS image data writing image data writing (a) virtual VGA device : The Logical VGA SnapShot function consists of the following three components. (a) Virtual VGA Device Virtual VGA device is used for the guest OS to write image data. For further information on the specifications, see the following table. The following virtual VGA device is required to the LPAR. Table 1-1 Virtual VGA Device Specifications Item Description VGA specification Standard VGA VBE3.0 (SVGA) Support mode (*1) VGA mode 720 x 200 pixels 16-color text mode (Mode03h) (*2) 640 x 480 pixels 16-color graphic mode (Mode12h) SVGA mode Resolution: 800 x 600; 1024 x 768 Color: 256 colors; 65536 colors; 16777216 colors Overview 1-3
(*1) If any other than VGA or SVGA mode is set, no snapshot image can be obtained. (*2) Strings the logical BIOS outputs to the text mode VGA are displayed also on the OS console (guest screen) of each LPAR. (b) Snapshot Image Acquisition Web Server Web server is incorporated inside the LPAR manager. By receiving a snapshot image acquisition request from the Web browser, the Web server will obtain and return the images in virtual VGA device to the Web browser. (c) External console External console operates the Web browser for displaying snapshot images. (2) Pre-settings for use of the Logical VGA SnapShot The following table shows the recommended settings on external consoles and the web browser on a server where you operate the Logical VGA SnapShot. 1-4 Overview
