Table 20 Cabling principles (Brick adds on strings) (continued)
Cabling principle
Applicability
Note: When adding a Brick to a Pillar Axiom 600 system, check
for the appearance of topology discovery tasks. Topology
discovery tasks are normal if they do not repeat or last more than
five minutes. If a topology discovery task completes and then
recurs after five minutes have passed, power off the last Brick that
was added to the Pillar Axiom 600 system and contact the Pillar
World Wide Customer Support Center for assistance.
Note: After adding a Brick, check the status of the LUNs. If any
LUN goes offline, power off the last Brick that was added and
contact the Pillar World Wide Customer Support Center for
assistance.
Alternate method for non-disruptive Brick add: (Used only when
recommended by the Pillar World Wide Customer Support Center)
Add the new Bricks to the rack along with the crossover cables.
Power on the Bricks and wait for the Bricks to initialize. Connect
the Bricks to the Pillar Axiom 600 system, one Brick at a time.
FIELD
The Brick type and the Brick model number must both be
compatible with the installed software version and the
compatibility matrix on the Pillar Axiom 600 system. If the Brick
type is supported and the Brick model number is not supported,
update the compatibility matrix to the appropriate version. If the
Brick type is not supported, the Pillar Axiom 600 software must be
updated before the Brick can be added to the system.
FIELD
After a successful Brick add, conduct the following checks:
● Verify that there is only one version of firmware for the Brick
type that was added. Also, verify that the firmware version is
correct for the installed Pillar Axiom 600 release.
● Verify that there are no topology discovery tasks in progress
and no repeating topology tasks.
● Verify that the system capacity has been increased by the
amount of storage available from the newly added Bricks.
Note: If any of the above-mentioned tests fail, contact the Pillar
World Wide Customer Support Center for assistance.
Tip: After the RAID controllers finish initializing, scrubbing
normally starts on the drives. Scrubbing causes all the drive LEDs
to blink rapidly even with no host I/O activity.
