Diskwarrior 5 1 – Popular And Powerful Disk Utility Box

Awarded 5 mice by Macworld magazine for an unprecedented 3rd time. Inducted into the iMore.com 2015 Hall of Fame for having 'saved countless Mac users from heartache.' Since 1998, DiskWarrior has won more awards than any other Mac disk utility. . DiskWarrior recovers your files including your photos, music and videos. DiskWarrior is the safest, most technologically advanced, most powerful utility to eliminate directory damage and recover your files, folders and documents. DiskWarrior is so advanced it can even recover your data from a failing hard drive.

What's New in DiskWarrior?

DiskWarrior 5 is now the one utility program that solves all of the common problems you'll likely encounter on your Mac. Just look at these new features:

• 64-Bit
Today's large disks can have large directories. Using the latest 64-bit technology allows DiskWarrior 5 to handle even the largest disks.

• Ships on a bootable flash drive to repair your startup disk
Flash drives start up much faster than DVDs and can be updated as needed.

• Includes the new DiskWarrior Recovery Maker
New Macs have new macOS startup requirements. DiskWarrior Recovery Maker updates your DiskWarrior Recovery flash drive with the latest macOS.

• Runs from macOS Recovery (Recovery HD)
In an emergency, you no longer need a separate startup disk to run DiskWarrior on your startup disk unless your startup disk has partition table damage.

• Repairs partition table damage
Sometimes the damage is to the map that describes all your drive's partitions which makes all your partitions unavailable. DiskWarrior 5 can repair standard Mac GUID partition tables when started from the DiskWarrior Recovery flash drive.

• New architecture
Updated to use the newest macOS technologies while still supporting older PowerPC* and Intel Macs that can no longer run the latest macOS.

• Significantly faster
For many disks, directory rebuilding is twice as fast as the previous version.

• Recovers more data from drives with hardware malfunctions
Recover your important files from most failing drives, possibly saving you thousands of dollars in professional recovery costs.

• Detects and repairs more disk problems than ever
The best is even better.

• New Directory Optimization Index
You can tell how efficient your directories are at a glance.

• Repairs Time Machine backup disks
Drives containing Time Machine back ups can have enormous directories that were often too large for DiskWarrior 4. The 64-bit memory addressing of DiskWarrior 5 allows these drives to be repaired or recovered.

• Plus a lot more
Purchase a new copy or upgrade now from older versions of DiskWarrior.

* Please note that to install DiskWarrior 5, your Mac must start up in Mac OS X Leopard (10.5.8) or later. This is a change from DiskWarrior 4 which supported installation on older versions of Mac OS X. Please read the system requirements for DiskWarrior 5.

HPACUCLI stands for HP Array Configuration Utility CLI.

As the name suggests, this utility is for HP servers.

Hpacucli is used to create, delete and repair the logical and physical drives on the smart array controllers in HP servers.
To use hpacucli, download and install the latest version of hpacucli rpm from the HP website on your Linux server.

1. Two ways to execute the command

When you type the command hpacucli, it will display a “=>” prompt as shown below where you can enter all the hpacucli commands explained in the article.

Or, if you don’t want to get to the hpacucli prompt, you can just enter the following directly in the Linux prompt. The following is exactly same as the above.

2. Display Controller and Disk Status

To display the detailed status of the controller and the disk status, execute the following command.

In this example, as shown in the above output, we have total 7 physical drives. The first RAID group RAID 1 contains 2 physical drives and the remaining physical drives are not assigned to any of the logical drives.

3. View Controller Status

To display the status of just the controller, do the following. In this example, the controller is working perfectly without any issues.

4. View Drive Status

To display the status of the physical drive, do the following. In this example, we have two 146GB physical drives, and 5 300GB physical drives, and all are in perfect condition.

5. View Individual Drive Status

To display the detail status of a specific physical drive, do the following.

In this example, we like to know the status of “pd” (physical disk) in slot 0. The specific disk is “2I:1:6”, which we figured it out from the output of the previous command.

As shown in the output below, this displays the Serial Number, Make, Model, Size and Fireware version of this specific disk. This can be very helpful during troubleshooting.

6. View All Logical Drives

The following command will display all available logical drives on the system. As shown in the output below, we currently have only one logical drive in RAID 1 with total size of around 136GB.

7. Create New RAID 0 Logical Drive

Execute the following command to create a new logical drive using RAID 0 option.

The above command creates a logical drive with the physical drives 1I:1:3 on RAID 0 configuration in slot 0.

8. Create New RAID 1 Logical Drive

Execute the following command to create a new logical drive using RAID 1 option.

The above command creates a logical drive with the two physical drives 1I:1:3 and 1I:1:4 on RAID 1 configuration in slot 0.

9. Create New RAID 5 Logical Drive

Execute the following command to create a new logical drive using RAID 5 option.

The above command creates a logical drive with the five physical drives on RAID 5 configuration in slot 0.

Once these logical drives are created, you should see the disks from the fdisk and you can format it from there and start using it.

After you create a logical drive, execute the following command to verify that the LD got created. In this example, it shows that the RAID 5 logical drive got created successfully.

10. Rescan for New Devices

If you’ve added new physical hard disk, they won’t automatically show-up immediately. You have to scan for new devices as shown below.

11. View Detailed Logical Drive Status

To display the detailed status of the logical drive, do the following:

The above shows the RAID type, the disk name assigned to the logical drive, and other information about the logical drive number 2.

12. Delete Logical Drive

To delete a logical drive with the number 2 use the below command.

13. Add New Physical Drive to Logical Volume

To add the new drives to existing logical volume, do the following.

In this example, we are adding two additional drives specified above to the logical volume number 2.

14. Add Spare Disks

To add the spare disks to arrays that can be used in case of disk failures on one of the logical drives, do the following:

In this example, we are adding two spare disks to the array.

15. Enable or Disable Cache

The below commands enable or disable cache for the entire slot.

16. Erase Physical Drive

Execute the following command to erase a physical drive in array B on slot 0.

17. Blink Physical Disk LED

To blink the LED on the physical drives for the logical drive 2, do the following. This will make the LEDs blink on all the physical drives that belongs to logical drive 2.

Once you know which drive belongs to logical drive 2, turn the LED blinking off as shown below.
