RSS Disk State = MIRRORED / RSS Disk State = NONE

Hi,

Please help:
How to rebuild the RSS Disk State of a Disk group in an EVA for it to become RSS Disk State = MIRRORED instead of =NONE.

Regards,

Re: RSS Disk State = MIRRORED / RSS Disk State = NONE

In an EVA disks are subgrouped in groups of 6 - 11 disks, usually 8. Each of these subgroups is a RSS and contains all the RAID information.

Parity = losing an enclosure will not destroy data
Mirrored = losing an enclosure will destroy vraid 5s but not vraid 1s
None = losing an enclosure will destroy vraids 1s and 5s.

As this depends on the location of the disks on the enclosures, the only way to change it is to physically move the drives.
