Intended Audience
These instructions are intended for Hitachi field personnel, and appropriately
trained authorized third-party service providers. To perform this procedure,
you must be able to:
• Use a terminal emulator to access the HNAS server CLI and Bali console.
• Log in to Web Manager (the HNAS server GUI).
• Migrate EVSs.
• Physically remove and replace fan assemblies and hard disks.
Note:
You may also be required to upgrade the firmware. See
for hard disk replacement on page 80
for information about the minimum
required firmware version.
Downtime considerations for hard disk replacement
Downtime is required because hard disk replacement is not a hot-swap
operation. Replacing a hard disk requires that you shut down the server,
disconnect the power cables from the Power Supply Units (PSUs), physically
replace server parts, and start the process of rebuilding the server's internal
RAID subsystem.
• Standalone server
The complete disk replacement process requires approximately 2.5 hours,
and the server will be offline during this time. You could restore services in
approximately 1.5 hours by restoring services before the second disk of
the server's RAID subsystem has completed synchronizing.
Caution: Early service restoration is not recommended.
If the
second disk of the internal RAID subsystem has not completed
synchronizing, and there is a disk failure, you may lose data. Do not
restore services before the RAID subsystem has been completely
rebuilt unless the customer understands, and agrees to, the risks
involved in an early restoration of services.
• Cluster node
The complete disk replacement process requires approximately 2.5 hours
for each node, and the node will be offline during this time. You can,
however, replace a node's internal hard disks with minimal service
interruption for the customer by migrating file serving EVSs between
nodes. Migrating EVSs allows the cluster to continue to serve data in a
degraded state. Using EVS migration, each EVS will be migrated twice,
once away from the node, and then to return the EVS to the node after
hard disk replacement.
