pasting characters, it is recommended that a large amount of characters
be divided into several blocks (up to the upper limit of characters per
block), and then be pasted.
When you connect the system to the virtual COM console and boot the
guest OS, Windows may halt its boot with the EFI screen; Linux may halt
its boot in the grub console; even though rarely. If it happens, press the
Enter key to resume the boot.
Notes on Operation
• Connect to the virtual COM console when needed in usual operation.
Virtual COM console response might stop when it stays connected to LPAR
manager. Reconnect the virtual COM console then. We recommend that
VC (virtual COM console) on the Logical Partition Configuration screen
should be assigned to an LPAR when needed and the assignment should
be released when not needed.
• If you repeatedly change settings for VC (virtual COM console) on the
Logical Partition Configuration screen with the virtual COM console
connected, the console screen may be disturbed. If so, perform Edit (E) >
Screen clear (S) in Tera Term to clear the screen, which can correct the
screen disturbance.
Logical VGA Snapshot
LP Web systems may display different contents depending on different LPAR
manager firmware versions.
Overview of Logical VGA Snapshot
LPAR manager supports the logical VGA snapshot with which users can view
and acquire images that the guest OS running on each LPAR outputs to the
display unit. With this function, images each LPAR outputs to the display unit
can be acquired at any time as snapshot images (still images). To do this,
access is made to the web server for acquiring snapshot images provided by
the LPAR manager, using the Web browser from an external console. The
following figure shows the logical VGA function configuration.
For details, see the Hitachi Compute Blade 500 Series Logical VGA snapshot.
Note that you can use the HVM management command (HvmSh) to disable
HTTP communications. To disable HTTP communications, you need to restart
LPAR manager. For details about the command, see the HVM Management
Command (HvmSh) Operation Guide.
LPAR manager uses a built-in certificate signed with SHA-1 in http
communications.
We do not recommend that you use the certificate owing to insecurity. We
recommend that you use the server certificate for LPAR manager, instead.
