One DS4300 and two or more storage expansion enclosures in a
mixed configuration
Note: Not all of the EXP100, EXP700, EXP710 or EXP810 enclosures can be
cabled together. For information on supported combinations, see “Supported
storage expansion enclosure configurations and intermix combinations” on
page 47.
When you plan to cable the DS4300 Storage Subsystem to storage expansion
enclosures that are in a mixed configuration, it is recommended that you cable the
same type of enclosures together. Since the EXP810s and EXP710s are generally
considered as the same type (enclosures with switched-ESMs type), these two
enclosure models must be grouped together if they are contained within a drive
loop. If a storage expansion type with non switched-ESMs, such as EXP100, is
cabled between the EXP710s and EXP810s, a " drive enclosure not cabled
correctly " error will be displayed in theDS4000 Storage Manager Recovery Guru.
