Storwize V7000 and SAN Volume Controller FlashCopy Replication Operations Involving Volumes Greater Than 2TB in Size Will Result in Incorrect Data Being Written to the FlashCopy Target Volume

If a Storwize V7000 or SAN Volume Controller FlashCopy mapping is started on Volumes greater than 2TB in size, this will result in the FlashCopy operation writing incorrect data to the target Volume. The target Volume will therefore not contain the same data as the source Volume.

Content

An issue has been discovered that will result in incorrect data being written to FlashCopy targetVolumes greater than 2TB in size.

Data on the source Volume will be unaffected by this issue. Any FlashCopy replicated Volumes less than 2TB in size will also be unaffected by this issue.

Customers are strongly advised not to perform any FlashCopy operations on Volumes greater than 2TB in size, until a fix is available and has been applied.

Customers should also be aware that any previously created FlashCopy target Volumes greater than 2TB in size will have incorrect data on them, and should be treated as inconsistent with the original source data.

Fix

This issue will be fixed in the upcoming 6.1.0.9 PTF release, and also in the next major release, 6.2.0.x.
