Had to do a bunch of SDRS migrations recently. This was in a 5.5 environment, so I’m not sure if this has been fixed in 6.0+, but when you kick off a heap of SDRS migrations in a row, vCenter doesn’t seem to factor in the impact of the already queued migrations.

Had a client who required in-guest iSCSI connections. After reviewing the physical NICs that were going to be available on each host, I created the following script to automate the creation of the virtual switch with associated uplinks and two portgroups. (more…)

Just a simple one here, but want to keep it on file. This will rebuild the tokenGroups attribute for a user, which is a dynamic attribute, i.e. not part of the schema. Useful for working out why people are getting token bloat and kerberos issues. (more…)
