IBM Storwize V3700 deleted LUN - Any previous experiences?

[-BR-]

IBM Storwize V3700, customer claims he deleted a LUN from a RAID5 pool using the web management
RAID5 has 9TB total size and 6 SAS 2Tb hdds

RAID-5 parameters should not be difficult to find (parity type, stripe, rotation, disk order, etc).
My concern is about some servers that like to split LUNs (fragment them, making not linear) across various RAID areas, making a disk-off recovery pita ...

Anyone had a previous experience with this unit?
Is this one of the "fragment happy" servers, or a linear one?

Thanks in advance

Storwize is a SAN (means that it is "fragment happy"), it supports tier-ing too.

Anyone with real experience in SAN (non-linear raid recovery) and interested in performing remote recovery please PM wth price quote
File system is VMFS with NTFS inside
I can also respond in PM with more tech details.

Please note that while standard linear RAID recovery experience is needed, it alone will not be able to recover requested files.
I´m quite good with linear raids, if it was possible only with linear raid experience I would already have done it myself.
So you would really need to have good experience with SAN raid recovery (non linear)

Could provide tv access to a pc connected on the same network to web management port and iSCSI mappings to the actual existing server volumes and/or also have all RAID5 6x 2TB SAS HDDs binary clone images files available.
