Hi,  Here they are specifiaclly referring to EMC Certification Data Erasure for Symmetrix Single Drive Erasure. Under this feature, If a drive fails and is permamnetly spared then data erasure automatically runs on the spare drive when replaced.  Regards Amita Wasson
Hi everyone!  I am interested in the data erasure capability of VMAX. However, while reading the VMAX Product Guide I came up with a question. In page 107 it is said: "Data erasure requires permanent sparing. Data erasure is invoked only upon successful completion of permanent sparing". Why should a process which basically deletes the data securely need permanent sparing?. If I understood well, permanent sparing is a process that replaces a defective drive with a spare drive, so I can't understand what it has to do with the removal of data. Someone can explain it to me please?  Thanks [IMAGE]
