You are here:
< All Topics

In cases where the SSD or in-server Flash card is connected through a Raid Controller, the storage device might not register as SSD device type in VMware, in which case the below commands need to be run to identify the device as SSD.
Say disk named naa.60000000000000000006200101000016 needs to be configured as SSD. (The Administrator can get the disk name using command esxcli storage core device list).

The below commands can be used to set this device as SSD

esxcli storage nmp satp rule add -s VMW_SATP_LOCAL –device naa.60000000000000000006200101000016 –option=enable_ssd

esxcli storage core claiming unclaim –type device –device naa.60000000000000000006200101000016

esxcli storage core claimrule load

esxcli storage core claimrule run
