IBM System storage DS6000 Series, Attachment Manual

Page: 93 / 298

You can define the storage unit LUNs as either protected or unprotected. From a
storage unit physical configuration view point, all IBM iSeries volumes are RAID-5
or RAID-10 volumes and are protected within the storage unit. When you create the
IBM iSeries LUNs by using the IBM TotalStorage DS Storage Manager, you can
create them as logically protected or unprotected. Table 5 shows the disk capacity
for the protected and unprotected models. To logically unprotect a storage LUN,
allow the iSeries host to perform remote load source mirroring to that device.
Because the load source is mirrored on an external LUN, the storage unit can copy
or transfer this load source as a disaster recovery backup. When you use the
iSeries tools kit, an iSeries host in a remote location, using a copy of the original
load source, can recover this load source and start running as if this recovery box
was the original source host.
