CommVault – Software Updates via HTTP/HTTPS

This is an early release feature that was slipped in without much fanfare. If you installed your CommCell using or after Version 11 SP5, you’ll be quietly downloading CommVault updates over HTTPS. For many of us though, our CommCells have evolved over various upgrades and downloads would be using FTP. While this has generally been ok, I’ve found it tends… Read more »

[Another] Cisco UCS Quick fix – ECC:Sensor Threshold Crossed

Another UCS issue that came up a while ago, again with an easy fix; ECC:Sensor Threshold Crossed Having a skim through the tech support bundle showed they were the good ECC errors, of the “correctable” kind, so replacement of parts was not a likely requirement. To clear these out, login to one of your FI’s, change the scope according to… Read more »

Cisco UCS Quick Fix – FFCH_ERROR_OLD_FIRMWARE_RUNNING

The following warning greeted me in the Cisco UCS Manager today; There was no issue on the host (an ESXi 5.5 server) and everything else on the host seemed normal. This was a recently commissioned B200 M4 server. The running firmware version is 2.25(b). A search on Quick View showed an entirely consistent match, noted as Cisco Bug: CSCut10525 https://quickview.cloudapps.cisco.com/quickview/bug/CSCut10525 … Read more »

Quick Fix – VMware WS: Windows cannot find the Microsoft Software License Terms.

CommVault – Upgrade DDB to Transactional Mode

The deduplication databases (DDB) are arguably the most important component in an efficient and fast CommVault environment. If you’ve ever had a Media Agent fail unexpectedly before the DDB’s were able to gracefully shutdown, you’d be well aware the the restore and rebuild times can be very long. In Version 11, there have been improvements made to the DDB architecture,… Read more »

AWS and PowerShell – Let’s be friends Part 1

I first used AWS approximately 4 years ago. At that time, programmatic management of services was not an easy hurdle to jump and required regular ‘feeding & watering’. Naturally, these tools have matured greatly so whatever tool-set you are most comfortable with has a well developed set of features/options available for you to use. These can be referenced and downloaded… Read more »

After receiving the codes this year and downloading the latest version, it should have been a simple process to install, right ? Dbl-Click, next, next, next…. ? Moments after confirming the UPGRADE dialog, i was surprised to see a warning;… Read more »

ESXi 5.5 – Automating VMFS UNMAP w/ PowerCLI and PowerShell

With vSphere 6.5 recently released, a nice feature was the automated execution of the UNMAP command against thin provisioned datastores to reclaim space. This requires no user interaction, it’s fully automated for you and can free up significant amounts of space from your datastores. There’s some good information regarding the v6.5 release  on these blogs; ESX Virtualization Vladan Seget VirtualizationIsLife  Anthony… Read more »

VMware DRS rule manipulation using PowerCLI (EMC VPLEX use case) Part 1.

VPLEX is another of my favourite products,  and for good reason. I currently run a Metro cluster underneath a VMware platform that has proven to be super reliable. One important design consideration for this is to ensure that VM’s are configured for site bias. Why ? Glad you asked. In a VPLEX Metro configuration, a VPLEX detach rule is defined… Read more »
