Hello,
i'm trying to add virtual flash capacity to esxi 5.5 u1 hosts but i've a problem.
SSD disks are correctly recognized, for example:
# esxcli storage core device list -d naa.600508b1001c99f0cf0a90cd43a1e2f5
naa.600508b1001c99f0cf0a90cd43a1e2f5

But when i try to add it via Web Client the task complete successfully but i still not have flash capacity added to my host.
What can be the problem?
Thanks for help,
Nicola
Hi, To set up a Virtual Flash resource: 1.In the vSphere Web Client, navigate to the host. 2.Click the Manage tab and click Settings. 3.Under Virtual Flash, select Virtual Flash Resource Management and click Add Capacity. 4.From the list of available SSD devices, select the SSD device to use for virtual flash and click OK. Note: After the Virtual Flash is created, the Device Backing area lists all SSD devices that you use for the Virtual Flash resource. Check if you are following the above correct step while adding the VF or else try to read the issue in the below link might help you. http://tomverhaeg.nl/vmware-esxi/vmware-esxi-tag-a-device-as-local-and-ssd
Hello, thanks for the replay.
I've already followed the link you posted but i'm not able to get virtual flash capacity added to the host.
The SSD is correctly recognised (as per previous screen shoots)
is local: true
is SSD: true
anyway, when i try to add it, the task complete successfully but at the end i've no capacity added.
Hi, Try to check with the command prompt from ESXi host server https://pubs.vmware.com/vsphere-55/topic/com.vmware.vsphere.storage.doc/GUID-B78037F1-2262-4853-9D72...
Hello, i've solved.
I've recreated logical disk and reformatted the SSD with the HP controller utility and then i've been able to add vf capacity.
Thanks for help.
