Increase the size of a volume on an EqualLogic PS4000XV SAN

You have a Windows 2008 R2 server that is nearly out of disk space on its ‘D’ drive. The ‘D’ drive is a volume on an EqualLogic PS4000XV Storage Area Network. This is a production server and the change needs to be done immediately in the middle of the day without service interruption. Whenever possible, I prefer to make changes like this outside of production hours or as scheduled downtime if you operate in a 24/7 environment since there is a chance that something could go wrong. When you Read more [...]

Updating the Firmware on an EqualLogic PS4000XV SAN

This blog will walk you through the steps of updating the firmware on an EqualLogic PS4000XV SAN (Storage Area Network) from version 4.3.0 to version 5.0.2. Plan the Update This process requires that the SAN be restarted so I recommend scheduling it outside of production hours or as scheduled downtime if you work in a 24/7 environment. I also recommend gracefully shutting down any servers that have data on the SAN since you would otherwise be ripping the drives out from underneath those servers. Login Read more [...]

Multipath I/O Installation on Windows 2008 R2 Server Core

To determine if the Multipath I/O feature has been installed, login to your core server and run oclist.exe: If you already know the name of the feature or role your looking for, you can save yourself some time by piping the output of the oclist.exe command to the find.exe command. The /I parameter makes the search case insensitive. To install the MultipathI/O feature, run “start/w ocsetup.exe MultipathIo”. The name of the feature is case sensitive. Running Start/W in front of the “OCSetup.exe” Read more [...]

iSCSI Initiator Configuration on Windows 2008 R2 Server Core

This blog will guide you through the necessary steps of connecting the iSCSI initiator on Windows Server 2008 R2 Server Core to an iSCSI target or volume on a Storage Area Network. I prefer server core for the host operating system on my Hyper-V virtualization servers, but some things such as the iSCSI Initiator settings are easier to configure through a GUI. Luckily Microsoft has included the iSCSI Initiator control panel applet as part of R2. Log into your server and launch iscsicpl.exe. The Read more [...]

Initial Configuration of a Dell EqualLogic PS4000XV SAN

Unpack your new Dell EqualLogic PS4000 Storage Area Network, install it in the server rack, and cable it up. A dedicated iSCSI network that is totally separate from your normal network is required. Depending on your existing environment, you could create a separate VLAN on existing gigabit Ethernet switches to separate the iSCSI traffic from normal network traffic or you could purchase two dedicated gigabit Ethernet switches and place them in a stacked configuration or connect them via a crossover Read more [...]
