In a previous post, I discussed potential topologies of vCenters in a SSO domain. In general I think I have gotten burned a lot from having multiple vCenters and PSCs in a single SSO domain, but when things are working it’s pretty nice to have a consolidated view. In my latest issue, I decided to… Read More »
In my last post, I shared some HCI Bench numbers in different configurations. Chen Wei (author of HCI Bench) thought the numbers were a bit low and offered to review my config and logs. He recommended decreasing the number of disks and threads, clearing the host cache and preparing the disks. Initially I just used the… Read More »
I built a small 4-node all-flash VSAN for a specific use at my company. We didn’t need high performance, but we wanted the space efficiencies of dedupe/compression plus erasure encoding (in our R5). Note that FTT=1, I could have tested FTT=2 for R1 but not for R5 so I didn’t bother. Equipment: 4xDL380 Gen9 servers… Read More »
In a previous post, I discussed how the Web Client makes it difficult to create hybrid diskgroups grouped by array controller. I provided a PowerCLI script to automate diskgroup creation for this case. With All-Flash, the same issues around array controller grouping exists. A new issue that I encountered is that the “new-vsandiskgroup” cmdlet that… Read More »
Update March 22, 2017: Added ” | Where-Object { $_.Type -eq “Folder”}” to primaryfolder.extensiondata.childentity (and the subfolder one) to filter the childentities to just folders. SRM added a feature in which you map folder inventories across vCenters by assuming the folders had the same name and same structure. I already had one method for replicating folder… Read More »
edit 07-27-2017: Updated the script with username/password variables and also dynamically determine srmserveraddr by checking the primary vcenter extension manager. This will not work if you have multiple SRM servers (ie, shared-site config) I hit some issues finding the addfoldermapping function through the api exposed with connect-srmserver cmdlet, so I decided to use WSDL based… Read More »
EDIT 07-26-2017: PowerCLI 6.5.1 seems to fix this issue with connecting but you still may have issues finding some cmdlets, I don’t have the latest SRM so I can’t test the API. I have been getting back into SRM scripting, this time with SRM 6.1. In a previous post, I discussed some strategies around how… Read More »
I had a situation where one of my SRM installs would not start. Support could not figure out the issue but thought that there may be something corrupted in the database. I had been reconfiguring my SRM installs anyways so I decided to uninstall. First off, uninstall and reinstall per http://pubs.vmware.com/srm-61/topic/com.vmware.ICbase/PDF/srm-install-config-6-1.pdf does not seem to… Read More »
After upgrading one of my vCenters to 6.0u1 (and subsequently to 6.0u2), I noticed that the vCenter log bundles progressively grew larger and larger. So large that I could no longer upload them to sftpsite.vmware.com through the browser. I had to upload the logs via FTP (which would often timeout). I asked support if there… Read More »
One of the downsides of the web interface is that it is very difficult to group the disks by array controller when creating a diskgroup. You would have to determine the disks manually and then manually select the disks. From my discussions with VMware TMMs, the only reason to have a diskgroup span PCI controllers… Read More »
