Replacement of hardware, Quick restore iso image, If complete data loss occurs – HP StoreOnce Backup User Manual
Page 176
Options for creating space include:
•
Review your backup jobs to see if you can reduce the size of backup or retention time.
•
Use the backup application job settings to overwrite or erase data.
•
Ensure Housekeeping is running and is keeping up with demand.
Reduced performance using Data in Flight Encryption
If Data in Flight Encryption is configured on the subnet, the system may experience decreased
performance. This is the expected behavior when using the IPsec protocol. View the network
configuration using the CLI net show config command to determine if Data in Flight is
configured; see the HP StoreOnce Backup system CLI Reference Guide.
Cannot access a storage shelf (HP StoreOnce 4xxx Backup systems)
If you disconnnect a storage shelf or enclosure, you must reconnect it to the same controller port(s)
to which it was originally connected.
If multiple storage shelves have been configured, you must power up with all shelves attached. If
one is not connected, none of the storage will start. Do not try to reconfigure, power off, connect,
and reboot.
The HP StoreOnce 4900 Backup has a system check; if it detects incorrect cabling, it will not mount
the data storage and it will not allow the StoreOnce services to start. This will be reported in the
system Events log.
NOTE:
HP StoreOnce 4210/20 and 4420/30 Backup only: Do not daisy chain storage shelves.
Replacement of hardware
In the unlikely event that replacement hardware is required to be installed, please consult the
Maintenance and Service Guide on
. This guide also contains
information about BIOS and RAID battery problems.
Quick Restore ISO Image
A Quick Restore (QR) ISO image is available to re-image the software on a StoreOnce appliance
to a known good state. It is only used, under guidance by HP Support, in the unlikely event of a
node’s root file system becoming corrupted or lost; for example if multiple OS disk failures have
occurred.
Refer to the Maintenance and Service guide for your product for more information about
downloading the Quick Restore media.
CAUTION:
If you want to upgrade an existing HP StoreOnce installation, always use the software
update from
do not use the QR ISO image.
CAUTION:
The QR process will delete all stored data and configuration settings returning your
product to factory default settings.
If complete data loss occurs
In the event of multiple disk failures on a single enclosure, all backup data will be lost. Therefore,
it is very important to replace disks quickly if disk failures do occur. This section explains how to
rebuild your storage in the event of a complete data loss. See also
If several disks fail (page 164)
After the failed disks have been replaced it will be necessary to remove the old filesystem
configuration and rebuild a new one as follows.
NOTE:
This process rebuilds the system to a clean, unconfigured system. It does not recover lost
data.
