HP Virtual Connect Enterprise Manager Software manual Preparing for a Linux server migration

•The primary storage controller is configured with drives attached.

•The destination server is booted to the Insight Control server migration ProLiant Boot CD ISO and is running the migration agent.

•Select Auto Boot option in step 3 of the migration wizard.

Destination virtual machine host or virtual machine prerequisites

If migrating to a destination virtual machine, verify that the following prerequisites are complete:

•Select one of the following:

◦Let Insight Control server migration create the virtual machine automatically, which will automatically create and boot the destination virtual machine using the server migration Virtual Machine Boot CD ISO.

◦Create the virtual machine manually, and then boot the virtual machine manually using the server migration Virtual Machine Boot CD ISO.

•Verify that the destination virtual machine host has sufficient system resources, including processor, memory, and disk space to host the migrated virtual machine guest.

•Temporarily disable any antivirus software auto-scans on the destination virtual machine host to prevent interrupting the migration process. Re-enable the antivirus software after the migration.

Preparing for a Linux server migration

The following sections list prerequisites for a Linux server migration.

•If a firewall is running on the source server and Source Agent deployment is required, see “Disabling firewalls” (page 19).

•Ensure that the SSH port is open when a firewall is in use or the server migration Source Agent may not be deployed successfully.

•Verify compliance with all minimum prerequisites. See “Minimum source server prerequisites for all migrations” (page 33).

•The 32-bit version of glibc is required to run the Linux server migration Source Agent. The library is present by default on 32-bit Linux installations, but you may need to install it manually on 64-bit Linux systems. The 32-bit version of glibc is available on your Linux OS installation CD/DVD.

•If X-Windows is configured on the source server, the 32-bit version of libXtst runtime library must be installed.

Source physical server prerequisites

If migrating from a source physical server, verify that the following prerequisites are complete:

•Comply with all minimum prerequisites as listed in “Minimum source server prerequisites for all migrations” (page 33).

•PermitRootLogin and PasswordAuthentication are set to Yes in the /etc/ssh/ sshd_config file and the sshd service is running.

•The GRUB Boot Loader is required as the primary boot loader on the source server.
