As you guys and girls may be aware, Trend DS 8 SP1 has been out since the 30th April.
DS 8 SP1 promises support for wildcard exclusions and also adds linux support via an agent for on-demand scanning. (no real-time scanning yet).
There is also the added benefit of fixing the HEAP_MAX_SIZE PSOD issue but still waiting confirmation on this.
We’ve been having a few ongoing issues with our Trend environment mainly due to a lack of care and attention since I installed 7.5 SP1 and upgraded to DS 8. Also Trend is not the easiest beast to get up and running correctly. A lot of this is down to the documentation. The install guide (Getting Started?) is too simplistic and the Best Practice documentation is confidential (go figure!) so I would definitely recommend professional services if you are think about buying Trend DS. And on the plus side you get someone to blame if anything goes wrong!
I thought the release of 8 SP1 would be a good oppurtunity to get the Trend boys onsite to blow away the existing DSM + database and install DS 8.0 SP1 from scratch.
Bear in mind this was a live cluster, so we effectively split the cluster in half and kept one half on DS 8 (with all the live VMs) and the other half was upgraded to DS 8 SP1.
We deployed a new VM, installed DSM 8 SP1 on a new database, prepared the ESXi hosts and deployed the new virtual appliances. Once the infrastructure was configured, the existing virtual machines were vmotioned onto the DS 8 SP1 hosts that were managed with the new 8 SP1 DSM.
This was a little tricky as you effectively had two DSM’s in operation on a single cluster – not recommended for long! The key to managing the VMs was to change the view to sort by host, then you could easily ignore all the unmanaged VMs on half the hosts that were not prepared.
Once the VMs were vmotioned across, we waited 5 minutes for their config to update (to ensure they still didn’t think they were being protected by a DS8 appliance) and then activated them on the new DS 8 SP1 virtual appliances on the new DSM.
After all the VMs were activated we could upgrade the remaining ESXi hosts and re-enable DRS to spread the VMs back across the cluster.
All in all it was a painless upgrade with no downtime and on the plus side Trend is looking much better.
If you have been through a few iterations of Trend DS and you’re having issues with high maintenance, VMs being unprotected, appliances going offline, etc I recommend this approach to clear out your infrastructure and database and start off fresh.
Yes you have to reconfigure your alerting and security profiles but its a small price to pay for a healthy, stable environment.
DS 8 SP1 — well recommended!
— UPDATE 11/06/2012 —
I have had confirmation from Trend HEAP_MAX_SIZE issue has been resolved in DS 8 SP1, but for now I’ve left the HEAP_MAX_SIZE variable set on all my ESXi hosts as it is still unclear in my mind whether this setting is no longer needed.
