The DS5100 and DS5300 locates the drives in the storage expansion enclosures
after you power on the configuration. Always connect power to the storage
expansion enclosures first and then connect power to the DS5100 and DS5300.
After you have powered on the configuration, use the DS Storage Manager client to
check the status of the new drives, correct any errors found, and configure the new
drives.
DS5100 and DS5300 drive cabling best practices and rules
Add storage expansion enclosures to the DS5100 and DS5300 drive ports in a
round-robin fashion. For example, if you have four EXP5000s to be cabled to the
DS5100 and DS5300, instead of cabling all four EXP5000s to one drive port of a
drive channel, distribute the enclosures to all drive ports, which results in one
enclosure per drive port of a drive channel. Table 18 on page 74 and Table 19 on
page 74 show the number of storage expansion enclosures per port and drive
channel when connecting EXP5060 expansion enclosure to the DS5100/DS5300.
Table 20 on page 74 shows the number of storage expansion enclosures per port
and drive channel when connecting EXP5000 storage expansion enclosures to the
DS5100/DS5300.
