Step 5—Connect the power cords
WARNING! To reduce the risk of electric shock or damage to the equipment:
Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
Do not route the power cord where it can be walked on or pinched by items placed against
it. Pay particular attention to the plug, electrical outlet, and the point where the cord extends
from the storage system.
The X9720 Network Storage System cabinet comes with the power cords tied to the cabinet.
Connect the power cords to the X9700cx first, and then connect the power cords to the X9700c.
IMPORTANT: If your X9720 Network Storage System cabinet contains more than two capacity
blocks, you must connect all the PDUs to a power source.
Step 6—Power on the X9700c and X9700cx components
Power on the X9700cx first, then power on the X9700c.
Step 7—Discover the capacity block and validate firmware versions
1. Power on the capacity block by first powering on the X9700cx enclosure followed by the
X9700c enclosure. Wait for the seven-segment display on the rear of the X9700c to read on.
This can take a few minutes.
2. If necessary, update the firmware of the new capacity block. See firmware release notes for
more information.
3. Run the exds_stdiag command on every blade to validate that the new capacity block is
visible and that the correct firmware is installed. See
more information about the command output.
4. To enable the X9720 system to use the new capacity, there must be entries for each LUN in
/dev/cciss on each file serving node. To determine whether the operating system on each
file system node has recognized the new capacity, run this command:
ll /dev/cciss/c0d* | wc -l
The result should include 1 1 LUNs for each 82-TB capacity block, and 19 LUNs for each
164-TB capacity block.
If the LUNs do not appear, take these steps:
Run the hpacucli rescan command.
Check /dev/cciss again for the new LUNs.
If the LUNs still do not appear, reboot the nodes.
IMPORTANT: If you added the capacity block to an existing system that must remain online,
reboot the nodes according to the procedure
the capacity block to an existing system that is offline, you can reboot all nodes at once.
The capacity block is pre-configured in the factory with data LUNs; however, there are no logical
volumes (segments) on the capacity block. To import the LUNs and create segments, take these
steps:
1. Run the ibrix_pv command to import the LUNs.
2. Run the ibrix_pv -p -h command to verify that the LUNs are visible to all servers.
