Classifying disks as SSD
An SSD can be an internal disk or external disk. You can manually classify any disk as SSD or HDD, change, and display the media type information.
You can set the media type and connection type for a disk using the following vxdisk setmedia command:
Command: vxdisk setmedia type=<HDD|SSD> [-x] <diskname | p#c#t#l#>
Here is an example of the setmedia type command showing how to set the media type of a disk:
C:\> vxdisk setmedia type=ssd -x harddisk4 Successfully set media type of specified disks.
Note:
If you do not specify the disk connection type as external, then by default, that particular disk is marked as internal.
You can get the media type and connection type information of the disk using the following vxdisk command:
Command: vxdisk diskinfo -e <diskname | p#c#t#l#>
Here is an example of the vxdisk diskinfo command displaying the new state:
C:\>vxdisk diskinfo -e Harddisk6 Disk information Device Name : Harddisk6 ...... ...
You can get the plex media type information for the given volume using the following vxvol volinfo command:
Command: vxvol -v volinfo <driveletter>
Here is an example of the vxvol command displaying the media type of plexes:
C:\> vxvol -v volinfo h:
Volume information
Name : v3 (H:)
DeviceName : \Device\HarddiskDmVolumes\SSDg\v3
DriveLetter : H:
Disk Group : SSDg
...
Names of the plexes are...
Plex 0 : v3-01
...
You can get the plex media type information for all the existing plexes using the following vxprint command:
Command: vxprint -l -p
Here is an example of the vxprint command displaying the media type of plexes:
C:\> vxprint -l -p
Diskgroup = BasicGroup
Diskgroup = SSDg
Plex : v3-01
info : len=102774784 KB
assoc : vol=v3 sd=Disk1-02
flags : ncolumn=1 StripeWidth=0
GUID : 72bdc94b-ded8-4f2f-9f30-2cdd8cabc764
type : layout=Simple
...
...A plex can have the following four media types:
: All subdisks of the plex reside on SSD disks.
: All subdisks of the plex reside on HDD disks.
: The subdisks of the plex reside on SSD and HDD disks.
: If some disks on the plex are not available.
