IMPORTANT:
It is important that failed disks are replaced promptly.
To ensure that you are alerted to disk failures, ensure that either or both of SNMP traps and email alerts
are configured. If a disk failure occurs, you will receive notification immediately and can replace the
disks.
Note the following:
• HPE StoreOnce 5100 System: All enclosures of storage must be working for the system to operate; if any
RAID set fails on any one enclosure due to exceeding the maximum number of failed disks then ALL data
is lost.
• HPE StoreOnce 3500 Series: All 12 disks are used for data storage with or without the license to expand
the storage capacity to 100%.
• HPE StoreOnce 3100 System: If more than one disk fails, then the data and operating system are lost and
a “Quick Restore” of the appliance OS will be required before the unit can be used again.
Hot spare disk and LEDs on the HPE StoreOnce 5100 System
Both the HPE StoreOnce 5100 System and any Capacity Upgrade enclosures have a hot spare disk in bay
12. If one disk fails in the RAID set, the hot spare disk automatically takes it place until the failed disk is
replaced. The behavior of the LEDs on the hot spare disk is as follows:
• Head server: The LED is off on the hot spare disk until it becomes active due to the failure of another disk
in the RAID set. It is flickering green when in use.
• Capacity Upgrade enclosure: The LED is solid green on the hot spare disk until it becomes active due to
the failure of another disk in the RAID set. It is flashing green when in use.
Ordering the correct replacement disk for a failed disk
IMPORTANT:
HPE strongly recommends replacing a failed disk with a fresh disk from the factory. Do not substitute a
disk from another RAID set.
HPE StoreOnce 5100 System: If a disk fails, it is important to identify whether the disk is in one of the two OS
disk bays or one of the storage disk bays. Different disks are used in the two locations and the carriers are
different.
Always quote the serial number and product number for the enclosure that contains the failed disk so that
support can replace the correct part.
