The HP Virtual Server Environment : Virtual Partition Example Scenario (part 7) - Configuring an nPartition and Virtual Partitions for Auto-Booting

The two vPars are now configured and running properly. However, the boot sequence for the vPar monitor and the two vPars requires manual interaction.

The HP Virtual Server Environment : Virtual Partition Example Scenario (part 6) - Creating the Second Virtual Partition, Booting the Second Virtual Partition

After booting the first virtual partition, the second will be created. Most of the options for creating the vPar are similar to those specified when creating the first vPar.

The HP Virtual Server Environment : Virtual Partition Example Scenario (part 5) - Virtual Partition States, Booting the First Virtual Partition

These states are helpful in interpreting the output of the vparstatus command and managing vPars. Listing 4 shows the zoo24 vPar is in the N/A state. In this case, the vPar monitor has not been booted, so the vPar can't be in any other state

The HP Virtual Server Environment : Virtual Partition Example Scenario (part 4) - Installation of Virtual Partitions

Installing Virtual Partitions is straightforward. The two most common methods used for installing the vPar software are (a) using an Ignite-UX server to install HP-UX and vPars together, and (b) installing and booting HP-UX and then installing the vPar software as a separate step afterward.

The HP Virtual Server Environment : Virtual Partition Example Scenario (part 3) - Planning for Virtual Partitions

Proper planning for vPars greatly simplifies the implementation process. Before performing any vPar tasks, the state of the server should be captured for future reference. At a minimum, output of the parstatus and ioscan commands should be saved or printed.

The HP Virtual Server Environment : Virtual Partition Example Scenario (part 2) - The Virtual Partition Environment

The environment for this scenario is an HP nPartition server. An nPartition with one cell, four CPUs, and 2GB of memory will host two vPars. See Table 1 for the details of the nPartition.

The HP Virtual Server Environment : Virtual Partition Example Scenario (part 1)

This example scenario consists of the following steps. These steps are covered in detail throughout the example scenario. There are many possible ways to deploy vPars, and the intent of this example is to illustrate just one of them.

The HP Virtual Server Environment : HP Virtual Partitions - Virtual Partition Terminology

Local Bus Adapter (LBA) is the hardware layer that can be assigned to a single vPar. The assignment of an LBA to a vPar assigns the I/O slot, the contained PCI card, and all devices attached to the PCI card.

The HP Virtual Server Environment : HP Virtual Partitions - Virtual Partitions Overview

HP Virtual Partitions (vPars) allows the hardware of a single server to be divided into separate entities, each of which is capable of running a distinct operating system

Microsoft Exchange Server 2010 : Managing Mailboxes (part 4) - Assigning a Mailbox to a User from the EMS

In a larger organization, you will probably want to streamline or script the creation of new mailboxes and/or user accounts. The EMS allows you to do this easily. For now, though, let's look at the example you just completed from the EMC graphical user interface.

Microsoft Exchange Server 2010 : Managing Mailboxes (part 3) - Assigning a Mailbox to More than One User

For most administrators, user accounts and mailboxes are created a few at a time rather than one at a time. The procedure for doing this using the EMC is almost identical to the procedure for assigning a mailbox to a single user.

Microsoft Exchange Server 2010 : Managing Mailboxes (part 2) - Using the EMC to Assign a Mailbox

Exchange Server 2010's management tools include a great new feature that will automatically assign a user to a mailbox database. This is a great feature for organizations that have trouble balancing mailboxes on mailbox databases; frequently a mailbox administrator will always select the first mailbox database in the list.

Microsoft Exchange Server 2010 : Managing Mailboxes (part 1)

The Exchange Management Console (EMC) allows you to associate a mailbox with an existing user in the Active Directory, or you can create the user account (if you have the necessary permissions).

Bare-Metal Recovery : Solaris Bare-Metal Recovery - Setup of a Noninteractive Restore (part 2) - Creating a Noninteractive Disk Image

If you wish to perform a noninteractive restore from an NFS mount, you should have a properly configured Solaris network boot server configured on your network and boot using the boot net – install command.

Bare-Metal Recovery : Solaris Bare-Metal Recovery - Setup of a Noninteractive Restore (part 1) - Noninteractive Setup Files, Creating a Noninteractive Tape Image

Jumpstart has been used for many years to automate the installation of Solaris. Flash archive uses some of the same technology as Jumpstart; for example, it uses the concept of the profile, rules, and sysidcfg files to provide for a noninteractive restore from a flash archive image.

Bare-Metal Recovery : Solaris Bare-Metal Recovery - Preparing for an Interactive Restore (part 2) - Bare-Metal Recovery with Flash Archive

The flash recovery is now complete. Once the system reboots, you may have to configure system information such as the node name and network information.

Bare-Metal Recovery : Solaris Bare-Metal Recovery - Preparing for an Interactive Restore (part 1) - Creating Flash Archive Images

The easiest way to get started using flash archive is to create backups for an interactive restore. This requires more work during the recovery process, but you’ll have a bootable backup in only a few minutes

We are no longer performing the processing in the class ThreadFunc. However, we will still use it to create the instances of the FileWorker class, set the options, and start the processing.

Windows System Programming : Exception Handling - Vectored Exception Handling

Exception handling functions can be directly associated with exceptions, just as console control handlers can be associated with console control events.

Windows System Programming : Exception Handling - Example: A Console Control Handler

The handler routine will put out a message, wait 10 seconds, and, it would appear, return TRUE, terminating the program. The main program, however, detects the exitFlag flag and stops the process.

Windows System Programming : Exception Handling - Console Control Handlers

Exception handlers can respond to a variety of asynchronous events, but they do not detect situations such as the user logging off or entering a Ctrl-C from the keyboard to stop a program. Use console control handlers to detect such events.

Microsoft Enterprise Library : Relieving Cryptography Complexity - Diving in with an Example (part 2) - Obtaining and Comparing Hash Values

To create and compare hash values, you use a hash provider. As you saw earlier, the Cryptography block includes several hash providers. The examples we provide use two of these: the SHA512 hash algorithm provider and the MD5Cng hash algorithm provider.
