Packet errors are often the cause of bad cable, bad switch ports and a misconfiguration on switch iSCSI ports. Once the volumes show as available in ESXi you can restart your VMs and be back up and running.First of all, make sure you run the latest version of FW and SANHQ table. Reverse the process you did in step 3 above and once they show as online you can then go into the VI client and tell each of your ESXi hosts to Rescan the iSCSI adapter(s). Put Volumes back online and rescan HBAs on ESXi hosts – Now we are just starting things back up.In the example shown below with 2 members each with redundant controllers the process took about 50 minutes to finish entirely.

This will take a series of restarts to take effect, 1 for each controller for each device. When each member is done it will prompt you to restart the device.
#DELL EQUALLOGIC SAN HQ UNABLE TO CONNECT TO ARRAY UPGRADE#
Simply click the Upgrade button on one of your members and the process will begin on ALL members.

It will then show you the Update dialog (as shown below). Once in the Update Firmware it will first ask you for your grpadmin password, then ask you to locate your update file. Perform update from the GUI (in PS Manager, Members> Device > Maintenance tab, Update firmware…)- Here’s where the rubber meets the road.

If you set the volumes as offline then you can be sure nothing will run there.
Download firmware from (requires account)- Equallogic is currently maintaining two active firmware paths, the 5.x path and the 6.x path.The actual act of updating is fairly simple and can be broken down into a few steps. PS Series) will all use the exact same firmware.
The good news is that all actively supported Equallogic arrays in a given series (i.e.

Keeping up to date on device firmware is critical to system performance as Dell is constantly improving the product through software fixes and enhancements. Finally Equallogic supplies a client/server management application called SAN Headquarters which allows you to monitor and manage your various storage groups and is overall a very handy tool to have. In current versions of VMware ESXi this is called the Multipathing Extension Module, allowing for you to essentially create a mesh network between your redundant iSCSI ports on your ESXi hosts and the redundant NICs on the arrays. Second, is the client operating system integration software for Windows or Linux (directly accessing the iSCSI from Windows or Linux) this are called the Host Integration Tools. This is also what updates the basic GUI for device configuration. The device firmware is what powers the actual disk arrays and is where most of your enhancement via update is found. Software for an Equallogic iSCSI environment can be thought of as split three ways. As we brought the 4100 online and pointed it at the controller of the existing device it was very simple to add to the existing device pool, quadrupling our storage capacity in a matter of minutes. As our storage needs grew (they always do) we recently added a PS 4100 to the array. In our case we started with a PS 5000 device a few years ago. Further when looking at iSCSI versus Fiber Channel you cost is even better in that you can typically leverage your existing switched infrastructure for your storage network, simply needing to VLAN off the storage connections from the rest of your network.Īdditions to the SAN with Equallogic arrays are very simple as well. In terms of value with our latest addition with a fully loaded system with 10k RPM SAS drives we were able to hit a price point of about $1300 per Terabyte, trust me when I say this is very cheap when compared to comparable systems from HP or EMC. Equallogic arrays in my opinion are a nice blend of value and performance that any systems or network administrator can learn to do basic setup and administration on in a few hours of poking around. In my environment we utilize Dell Equallogic PS Series iSCSI devices for our storage needs.
