Hyper to Meta ?
Hi Everyone,
I want to grow my simple device (hyper) but for expansion device should be a Meta device.
I can make my hyper as meta head and create a Meta.(Concat)
But, is it recommended, will there be any impact on data integrity of existing data on hyper?
Thanks

HI,
If you are making a concat meta, keeping the existing hyper (data) as meta head then there will be no impact to the existing data.
the subsequent devices (other than head) will not preserve data (possible data integrity issue).
refer to the array cli guide for more information.
regards,
Saurabh

Just a small correction: a device is not a hyper! A device consists of multiple hypers / slices. 1 Hyper is a slice of 1 disk. Several hypers put together are called a device. For a 3RAID5 device you'd need 4 hypers.

Agree, hyper is an hardware entity while device is an logical.
“Hyper Volume” and “split” refer to the same thing (a portion of a Symmetrix physical disk), a
“Symmetrix Logical Volume” is a slightly different concept. A Symmetrix Logical Volume is an
abstraction of a disk drive that is presented to a host via a Symmetrix channel director port. As far as
the host is concerned, the Symmetrix Logical Volume is a physical drive.
Different ppl uses different terminology.
Thank you!!
