SRDF Migration - Larger R2

Hello,

IHAC that moved from 39322 cyl hypers on DMX3/4s to 39324 cyl on VMAXs. Can we migrate the old hypers (and metas) to the new ones using SRDF seamlessly or is their host remediation required ? Or are their any other known issues using SRDF for migration in such a scenario ?

Thanks,

Girish

This is documented in the Solutions Enabler SRDF CLI guide,

All swap and SRDF/Star operations are blocked.
If SYMAPI_RDF_CREATEPAIR_LARGER_R2 is set to DISABLE in the options file, all operations are blocked.
Data mirrored to a larger R2 device cannot be restored back to its R1 device.
Concatenated metadevices are not supported but striped metadevices are supported.

Note: Depending on the type of file system and attached host, certain host-dependent operations may be required to access data migrated to a larger R2 device.
