Limitations of Flexible Storage Sharing

Note the following limitations for using Flexible Storage Sharing (FSS):

  • Disk initialization operations should be performed only on nodes with local connectivity to the disk.

  • FSS does not support the use of boot disks, opaque disks, and non-VxVM disks for network sharing.

  • Hot-relocation is disabled on FSS disk groups.

  • FSS does not support non-SCSI3 disks connected to multiple hosts.

  • FSS supports only those instant data change objects (DCOs) that are either created using the vxsnap operation or by specifying the logtype=dco and dcoversion=20 attributes during volume creation.

  • By default, creating a mirror between SSD and HDD is not supported through vxassist, as the underlying media types are different. To workaround this issue, you can create a volume with one media type, for instance the HDD, which is the default media type, and then later add a mirror on the SSD.

    For example:

    # vxassist -g diskgroup make volume size init=none

    # vxassist -g diskgroup mirror volume mediatype:ssd

    # vxvol -g diskgroup init active volume
