8 Reinstall one disk module in each redundancy group (one odd slot and one even slot) and wait until the disk format operation is complete and the disks come online. Use Command View to monitor the disk status. When the disks have come online, repeat this step for the next set of disks. Repeat until all disk modules have been installed. Note There is only one redundancy group on the VA 7110, so only one disk module at a time should be installed. 9 Check the status of the array to ensure it is operating normally. Note If the disk enclosure was installed on a VA 7400 and the LUNs on the array are no longer visible, it indicates that the FC Loop Speed switches were not set to 1GB/s as instructed in step 2. Power off the disk enclosure and repeat the above procedure. If the disks in the new enclosure are formatted with 512-byte sectors, they will be reformatted to 520-byte sectors. This process may take up to 60 minutes to complete, depending on disk drive capacity and system availability. See Table 23 on page 99 for raw format times. During this time, the green disk activity LED will be flashing. Upgrading Single to Dual Array Controllers (HP Service Personnel Only) Caution To prevent data loss, it is recommended that a full backup be performed before starting this procedure. An array with a single array controller can be upgraded to a dual array controller configuration by adding an upgrade array controller. To upgrade from a single to a dual array controller configuration: 1 Install DIMMs (ordered separately) on the upgrade controller. See "Installing an Array Controller DIMM" on page 120. 2 Install the upgrade array controller. See "Installing an Array Controller" on page 110. 134 Servicing & Upgrading

Servicing & Upgrading
8
Reinstall one disk module in each redundancy group (one odd slot and one
even slot) and wait until the disk format operation is complete and the disks
come online. Use Command View to monitor the disk status.
When the disks have come online, repeat this step for the next set of disks.
Repeat until all disk modules have been installed.
Note
There is only one redundancy group on the VA 7110, so only
one disk module at a time should be installed.
9
Check the status of the array to ensure it is operating normally.
Note
If the disk enclosure was installed on a VA 7400 and the LUNs
on the array are no longer visible, it indicates that the FC Loop
Speed switches were not set to 1GB/s as instructed in step 2.
Power off the disk enclosure and repeat the above procedure.
If the disks in the new enclosure are formatted with 512-byte
sectors, they will be reformatted to 520-byte sectors. This process
may take up to 60 minutes to complete, depending on disk drive
capacity and system availability. See
Table 23 on page 99
for
raw format times. During this time, the green disk activity LED
will be flashing.
Upgrading Single to Dual Array Controllers
(HP Service Personnel Only)
Caution
To prevent data loss, it is recommended that a full backup be
performed before starting this procedure.
An array with a single array controller can be upgraded to a dual array
controller configuration by adding an upgrade array controller.
To upgrade from a single to a dual array controller configuration:
1
Install DIMMs (ordered separately) on the upgrade controller. See
"Installing an Array Controller DIMM" on page 120
.
2
Install the upgrade array controller. See
"Installing an Array Controller" on
page 110
.
