Can I mark a local RAD1 as SSD when the ESX is not recognizing it as one in 7.0.3?
This is a pair of Dell SSD in RAID1 (EXS+datastore1)
I looked here: https://kb.vmware.com/s/article/2013188 but the article is for nmp and my RAID does not show in nmp.
Here is my config:
[root@ESX02:~] esxcli storage core device list -d naa.62cea7f0c4cce400298be079e4cd3c7d naa.62cea7f0c4cce400298be079e4cd3c7d Display Name: Local DELL Disk (naa.62cea7f0c4cce400298be079e4cd3c7d) Has Settable Display Name: false Size: 457344 Device Type: Direct-Access Multipath Plugin: HPP Devfs Path: /vmfs/devices/disks/naa.62cea7f0c4cce400298be079e4cd3c7d Vendor: DELL Model: PERC H730P Adp Revision: 4.30 SCSI Level: 5 Is Pseudo: false Status: on Is RDM Capable: true Is Local: true Is Removable: false Is SSD: false Is VVOL PE: false Is Offline: false Is Perennially Reserved: false Queue Full Sample Size: 0 Queue Full Threshold: 0 Thin Provisioning Status: unknown Attached Filters: VAAI Status: unsupported Other UIDs: vml.020000000062cea7f0c4cce400298be079e4cd3c7d504552432048 Is Shared Clusterwide: false Is SAS: true Is USB: false Is Boot Device: true Device Max Queue Depth: 64 No of outstanding IOs with competing worlds: 32 Drive Type: logical RAID Level: RAID1 Number of Physical Drives: 2 Protection Enabled: false PI Activated: false PI Type: 0 PI Protection Mask: NO PROTECTION Supported Guard Types: NO GUARD SUPPORT DIX Enabled: false DIX Guard Type: NO GUARD SUPPORT Emulated DIX/DIF Enabled: false [root@ESX02:~]
is a Raid1-array - not a SSD
Yes you can mark it as SSD if you like or have a need fore. If there is already ESXi content like .locker, ha or other system related stuff on it you will get an error and a host reboot is needed to take changes effect. If not than ESXi can do it on the fly during runtime.
Does is make sense? Most likely not because speedwise it does not make any difference. ESXi needs to know if its a SSD when you would like to use a disk for Cache,Swap or ....
