The number of HyperSwap volumes supported per IBM Storwize V5000 system (for V5030) is  1024. More FlashCopy requirements can reduce the number of possible HyperSwap  volumes.  For more information about the configuration limits search for “Configuration Limits and  Restrictions for IBM Storwize V5000” at  IBM Knowledge Center. Consider the following points: Note:  For more information about HyperSwap, see  IBM Storwize V7000, Spectrum  Virtualize, HyperSwap, and VMware Implementation , SG24-8317. GLYPH<SM590000> IBM FlashCopy Manager is not supported by HyperSwap volumes.  GLYPH<SM590000> The Remote Copy relationship must be removed first for a reverse FlashCopy operation.  After a reverse FlashCopy, all HyperSwap functions must be implemented manually again  (Remote Mirror + FlashCopy relationships).  GLYPH<SM590000> FlashCopy usage can be complicated because the Metro Mirror source volume and target  volume can switch during daily operation. Because of this possibility, the identification of  the copy direction is required for a successful FlashCopy.  GLYPH<SM590000> Hosts that access a HyperSwap volume through internet Small Computer System  Interface (iSCSI) or serial-attached SCSI (SAS) cannot take advantage of the high  availability function.
