1. Make sure that the DS3500 storage subsystem status is Optimal in the DS
Storage Manager software.
2. Use the expansion enclosure Rack Installation Instructions document to install
the new expansion enclosure in the rack.
3. Connect the power cables to the new expansion enclosure.
4. Power-on the expansion enclosure.
5. Connect one end of a Serial Attached SCSI (SAS) cable to the Drive
expansion port on Controller A in the DS3500 storage subsystem.
6. Connect the other end of the SAS cable to either of the In ports on the left
ESM in the expansion enclosure.
7. Connect one end of a second SAS cable to the Drive expansion port on
Controller B in the DS3500 storage subsystem.
8. Connect the other end of the second SAS cable to the In port on the right
ESM in the expansion enclosure.
9. Wait until the storage subsystem status is Optimal in the DS Storage Manager
software before proceeding to step 10.
10. Add the hard disk drives to the expansion enclosure. Make sure that you wait
at least 30 seconds for the DS Storage Manager software to recognize each
newly added drive before you install another drive.
To add additional expansion enclosures after the first expansion unit is connected to
a dual-controller DS3500 storage subsystem that is running, complete the following
steps:
1. Make sure that the storage subsystem status is Optimal in the DS Storage
Manager software.
2. Use the expansion enclosure Rack Installation Instructions document to install
the new expansion enclosure in the rack.
3. Connect the power cables to the new expansion enclosure.
4. Power on the expansion enclosure.
5. Connect one end of a Serial Attached SCSI (SAS) cable to the In port on the
left ESM in the expansion enclosure that is being added to the configuration.
6. Connect the other end of the SAS cable to the Out port on the left ESM in the
last expansion enclosure in the configuration (this expansion enclosure is
directly connected to the Drive expansion port on controller A of the DS3500).
7. On the last expansion enclosure in the configuration, disconnect the SAS cable
from the In port on the right ESM and connect it to the In port on the right
ESM on the new expansion enclosure that is being added to the configuration.
Note: When the SAS cable is disconnected in step 7, a loss of path
redundancy occurs and an error message is displayed in the DS
Storage Manager Recovery Guru. Disregard the error message. The
redundant path is restored in step 8 after the SAS cable is connected.
8. Connect a SAS cable to the Out port on the right ESM of the new expansion
enclosure and connect the other end to either of the In port on the right ESM
in the expansion enclosure that was previously connected to controller B of the
DS3500.
9. Wait until the storage subsystem status is Optimal in the DS Storage Manager
software before proceeding to step 10.
10. Add the hard disk drives to the expansion enclosure. Make sure that you wait
at least 30 seconds for the DS Storage Manager software to recognize each
newly added drive before you install another drive.
