With November 2015 public CAs do not issue new certificates that uses internal names or reserved IP addresses in
subjectAltName or in
commonName. Furthermore such certificates will be revoked on October 1st, 2016.
Internal names are hostnames that do not end with an Top Level Domain ending (.com, .de, …). For example: .local, .internal. Also NetBIOS names without any domain extension are affected.
Reserved IP addresses are defined by Internet Assigned Numbers Authority (IANA). You can look reservations for IPv4 here (RFC 1918 range) and IPv6 here (RFC 4193 range).
If you are using an internal CA you are not affected. For more information about this change of public CAs click here. For more information about VMware products click here.

convince the host that there is a SSD (if there is a really one)
- search for the SSD using:
esxcli storage nmp device list
you will get a satp-type and a device-id. The satp-type can be used to mark a remote disk as SSD. In the case of VSAN, SSD should be local.
- mark the disk as SSD:
esxcli storage nmp satp rule add --satp=VMW_SATP_LOCAL --device=device-id --option="enable_ssd enable_local"
- Accoring to KB you have to reboot the host, but it works without too.
- unclaim the disk
esxcli storage core claiming unclaim --type=device --device=device-id
- claim the disk again (it is another order than in KB)
esxcli storage core claimrule load
esxcli storage core claimrule run
esxcli storage core claiming reclaim -d device-id
- check the result
esxcli storage core device list -d device-id

clear partition form disks before add to VSAN
if you get errors by adding disk to VSAN, old partitions can resist on the disk. TAKE CARE TO CLEAR THE RIGHT DISKS!! To clear them do:
- check for partition
partedUtil getptbl /dev/disks/mpx.vmhban\:Cn\:Tn\:Ln
- delete them
partedUtil delete /dev/disks/mpx.vmhban\:Cn\:Tn\:Ln N
with N is the number of the partition listed with command before
