RAID 6 provides similar space benefits to RAID 5, with the additional protection of being able to survive the loss of up to two drives. P4000 SAN Solution user guide...
Page 58: Mixing Raid Configurations
NOTE: If you are protecting volumes across a cluster, configuring the storage system for RAID 1 or RAID 10 consumes half the capacity of the storage system. Configuring the storage system for RAID 5 or RAID 50 provides redundancy within each storage system while allowing most of the disk capacity to be used for data storage.
Page 59: Setting Raid Rebuild Rate
Reconfiguring RAID on a storage system or a VSA destroys any data stored on that storage system. For VSAs, there is no alternate RAID choice, so the only outcome for reconfiguring RAID is to wipe out all data. P4000 SAN Solution user guide...
Page 60: To Reconfigure Raid
• Changing preconfigured RAID on a new storage system RAID must be configured on individual storage systems before they are added to a management group. To change the preconfigured RAID level of a storage system, make the change before you add the storage system to a management group.

Page 71: Using Repair Storage System
In hot-swap storage systems configured with RAID 1, RAID 10, RAID 5, RAID 50, or RAID 6, a faulty or failed disk can be removed and replaced with a new one. RAID will rebuild and the drive will return to Normal status. P4000 SAN Solution user guide...
Page 72: Preparing For A Disk Replacement
CAUTION: Before replacing a drive in a hot-swap storage system, always check the Safe to Remove status to verify that the drive can be removed without causing RAID to go Off. When RAID is Normal in RAID 1, RAID 10, RAID 5, RAID 50, or RAID 6, all drives indicate they are safe to remove.

Page 80: Getting There
• Some network changes cause the storage server to restart the SAN/iQ services, making the storage system unavailable for a short time. Check the Availability tab for each storage system to see if any volumes will become unavailable if the services restart on the storage system. Volumes and snapshots may become temporarily unavailable while services restart.

• Adaptive Load Balancing (ALB). The logical interface balances data transmissions through both NICs to enhance the functionality of the server and the network. Adaptive Load Balancing auto- matically incorporates fault tolerance features as well. P4000 SAN Solution user guide...
Page 88: Best Practices
Best practices • Adaptive Load Balancing is the recommended bonding method, as it combines the benefits of the increased transmission rates of 802.3ad with the network redundancy of Active-Passive. Adaptive Load Balancing does not require additional switch configurations. • Verify and, if necessary, change the Speed, Duplex, Frame Size, and Flow Control settings for both interfaces that you plan to bond.

Eth0 fails, Eth1 changes from Passive (Ready) to active. Eth0 changes to Passive (Failed). Once the link is fixed and Eth0 is operational, there is a 30–second delay and then Eth0 becomes the active interface. Eth1 returns to the Passive (Ready) state. P4000 SAN Solution user guide...

Page 214: Single Snapshots Versus Scheduled Snapshots
Best practice: Use SmartClone volumes. See Chapter 14 on page 233 . Single snapshots versus scheduled snapshots Some snapshot scenarios call for creating a single snapshot and then deleting it when it is no longer needed. Other scenarios call for creating a series of snapshots up to a specified number or for a specified time period, after which the earliest snapshot is deleted when the new one is created (snapshots created from a schedule).

Page 315: A Replacing Disks Reference
For confirmation on which disks need to be replaced, contact customer support. Prerequisites • All Network RAID-10, Network RAID-10+1, Network RAID-10+2, Network RAID-5, and Network RAID-6 volumes and snapshots should show a status of Normal. Network RAID-0 volumes may be offline. P4000 SAN Solution user guide...
Page 316: Replacing Disks
• If volumes or snapshots are Network RAID-0 and online, change them to Network RAID-10 or other Network RAID level before replacing the disk. • If the cluster does not have enough space for the replication, take a backup of the volumes or snapshots, and then delete them from the cluster.

The storage system appears in the management group and the icon in the navigation window flashes for a few minutes as it initializes. Restarting a manager Before proceeding, make sure that the storage system has finished initializing and is completely added to the management group. P4000 SAN Solution user guide...
Page 320: Add Repaired System To Cluster
If necessary, ensure that after the repair you have the appropriate configuration of managers. If there was a manager running on the storage system before you began the repair process, you may start a manager on the repaired storage system as necessary to finish with the correct number of managers in the management group.
