Introduction This document describes the steps necessary to recover your Dell™ PowerVault™ Data Protection Solution from a number of hardware or software failures.
Introduction
Recovery Solution Map This document is comprised of sections describing specific recovery topics and procedures. Table 2-1 shows how each failure type potentially affects the various DPM components, and which section in this document is applicable to the specific failure type. As you explore different failure/recovery scenarios, keep the following guidelines in mind: • Re-installation of the operating system usually requires you to reinstall all of the applications on your system.
Table 2-1. Recovery Solution Map Potentially Affected System Components Failure Type RAID Group Operating OMSA System X Operating System X DPM Wizard DPM DB Use the Application or following Replicas sections to resolve these issues. (See the section titles below Table 2-1.
Recovering from Disk Failures Your system's internal disk storage has been pre-configured as RAID 5. Additionally, as described in the Dell PowerVault Data Protection Solution Storage Expansion Guide, any additional disks you add to your system will be configured as RAID 5. RAID 5 provides uninterrupted operation of your system in the event a single disk drive in the group fails. However, until the failed disk drive has been replaced, your system will operate in degraded state.
Figure 3-1 shows how disk status is reported in OMSA. Figure 3-1. Physical disk status Dell OpenManage™ IT Assistant Dell OpenManage™ IT Assistant is a central monitoring console, which can be used to monitor the status of your Dell systems running OMSA. Refer to the Dell OpenManage™ IT Assistant User's Guide for more information on installing and using IT Assistant. Replacing Disks When replacing hard drives, only use hard drives included in the Dell PowerVault Data Protection Solution Support Matrix.
Replacing Internal Disks To replace your system's internal disks, refer to the "Hard Drives" and "Replacing a Hard-Drive Carrier" sections of your system's Hardware Owner's Manual. Replacing Disks in an External Storage Enclosure To replace disk drives in an external Dell storage enclosure, refer to your storage enclosure's Hardware Owner's Manual.
Figure 3-2. Rebuilding a RAID 5 disk group If you had installed a global hot spare allocated to the same PERC adapter of the failed disk, the RAID group will automatically switch the role of the failed disk with the hot-spare disk, and begin the rebuild operation automatically. In this case, you would need to replace the failed disk and assign it as the new global hot spare for that PERC adapter.
Multiple Disk Failure Recovery If your system experiences multiple disk failures within the same RAID group and the RAID group contained your operating system and DPM application, you must reinstall the operating system and DPM application. If the RAID group contained the DPM replicas, you can restore the replicas from your tape archive. Replicas also can be restored from a secondary DPM server, protecting your primary DPM server.
Recovering From Disk Failures
Operating System Reinstallation This section describes the process of reinstalling the operating system on your PowerVault system. NOTE: Your operating system was pre-installed when you purchased your system. Only perform the steps in this section if required to repair a non-functioning operating system. Using the Dell Systems Build and Update Utility Use the Dell Systems Build and Update Utility CD that came with your solution to reinstall the operating system.
