Dell PowerVault DL2000 - Manual (Page 38)

Replacing Disks
When replacing disks, use only supported disks identified in the Dell PowerVault DL Backup to Disk Appliance
Interoperability Guide . Ensure that you replace the failed disk with a new disk of the same or greater capacity. If drives
of greater capacity are used, some usable disk space is lost in the RAID configuration.
• Internal disks—To replace the appliance's internal disks, see the Dell PowerVault DL2 xxx Hardware Owner's
Manual at support.dell.com/manuals.
• Disks in a storage enclosure—To replace disk drives in a storage enclosure, see the storage enclosure’s
Hardware Owner’s Manual at support.dell.com/manuals.
Recovering The Appliance System Disk Using IDR
NOTE: This section applies to DL appliances running Backup Exec versions prior to Backup Exec 2012. For Backup
Exec 2012 and later, see the topic "Recovering The Appliance System Disk Using SDR" .
If a disaster renders the system unusable, use IDR to recover the system to its last saved good state. The state of the
recovered system is based on the date and time the following items were last created:
• IDR CD
• Full backup of the appliance
• Full backup of the optional DSF
• *.DR file
CAUTION: Repair or replace any failed hardware prior to recovering the system using IDR.
CAUTION: If you are replacing the system, the hardware configuration of the replacement PowerVault DL2 xxx must
match the failed one. The replacement system must have the same storage controllers, type and number of internal
hard disks, network controllers, and so on.
To recover the appliance system disk using IDR, follow the steps below:
1. Ensure that the disk storage containing the full backups of the appliance is attached to the system.
2. Locate the most current *.DR file for the appliance located where specified in step 2 in the topic “Preparing The
System to Use IDR”. The *.DR filename is based on the network hostname of the appliance to be recovered.
3. Copy the *.DR file to removable media such as a USB key or ensure that the file can be accessed from the same
network as the system to be recovered.
4. Insert the bootable IDR media that you created into the DVD drive of the PowerVault DL2 xxx to be recovered.
NOTE: If you replace a PERC adapter on a failed appliance or if the replacement PowerVault DL2 xxx system
contains one or more new PERC adapters, see the topic “Importing Foreign Virtual Disks During IDR Recovery”
before you continue.
5. Boot the appliance.
6. During the initial boot up sequence, press <F11> to enter BIOS Boot Manager and select the CD/DVD drive (listed
as SATA Optical Drive) as the boot device.
The appliance boots up into the IDR Recovery wizard, which takes you through the steps necessary to recover the
appliance.
7. When prompted to select the recovery file, browse to the *.DR file on the removable media or network location in
step 2.
8. In Select Restore Method, select Use locally attached media device to recover from the full appliance backup data
created in the topic "Backing Up The Appliance System Files".
9. In the Modify Hard Disk Layout dialogue box, click Run Disk Management.
