Connecting the third Capacity Expansion Kit (JBOD 4)
NOTE:
For ease of illustration we have called the existing storage enclosure, Enclosure #2 and the daisy-chained
enclosure Enclosure #4. This numbering convention relates solely to the sequence in which the
enclosures are cabled. Within the StoreOnce software this enclosure is added to Storage Cluster 2 and
volume and pool names have C3 as part of their naming convention, for example: Pool C3_P7 to Pool
C3_P12.
For new installations before the StoreOnce 5500 System has been powered up for the first time, the only
requirement is to connect the enclosures according to the JBOD sequence identified on the label. See
on page 35 for a cabling overview of a fully expanded system.
For existing installations where the StoreOnce 5500 System is powered on, follow the step-by-step
sequence described in this section. It is necessary to disconnect existing SAS cabling to daisy chain
Enclosure #4 to Enclosure #2 (the second additional Capacity Expansion Kit to the enclosure that is
connected to the RAID controller card in slot 2).
WARNING:
Never disconnect all SAS cabling at the same time while the system is powered on. It is essential to
maintain an active SAS connection throughout the expansion process.
Procedure
1.
If Remote Support via STaTS is configured, use the following StoreOnce CLI command to put the
StoreOnce System into maintenance mode and prevent a support case being generated:
system enable remoteeventsuppression “4th JBOD Capacity Upgrade”
2.
Use the two supplied 0.5 m SAS cables for the inter-drawer connections, as illustrated below.
