Table 1 provides formulas for calculating your column count (assuming that you have fewer SSDs than HDDs and that you temporarily ignore any SSDs used for journal disks). Round the results down to the nearest whole number.

Whether or not your storage system is enclosure aware affects the number of columns that are required for automatic virtual disk repairs. When the ability to tolerate an enclosure failure (called enclosure-awareness) is enabled, Storage Spaces writes each copy of data to a different enclosure. That way, if one enclosure fails or goes offline, the data remains available in one or more alternate enclosures.

For enclosure awareness, each JBOD enclosure must contain the same mix of disks and must support SCSI Enclosure Services (SES), and you must deploy enough JBODs to allow for the failure of an entire enclosure without service interruption. The number of JBODs required will vary based on the resiliency setting for the storage pool (2-way mirror, 3-way mirror, or, in Windows Server 2012 R2 only, dual parity). For more information, see \"What types of storage arrays can I use with Storage Spaces\" in Storage Spaces Frequently Asked Questions (FAQ).

In Windows Server, you can often identify a failed physical disk by turning on an LED indicator on the storage enclosure. However, on most home systems, the physical disks typically don't have LED indicators; you might have to identify a failed physical disk by its serial number.

On a scale-out file server (SOFS), the cluster disk number assigned to a device drive can be different on different cluster nodes. In those cases, the more reliable method for identifying the disk is to use the GUID (described above).

Now, if you run Get-PhysicalDisk on any of the nodes, you'll see all the disks that were in the pool. For example, in a lab with a 4-Node cluster with 4 SAS disks, 100GB each presented to each node. In that case, after Storage Space Direct is disabled, which removes the SBL (Storage Bus Layer) but leaves the filter, if you run Get-PhysicalDisk, it should report 4 disks excluding the local OS disk. Instead it reported 16 instead. This is the same for all nodes in the cluster. When you run a Get-Disk command, you'll see the locally attached disks numbered as 0, 1, 2 and so on, as seen in this sample output:

Use the SerialNumber parameter to specify the disk you need to set to Healthy. You can get the serial number from WMI MSFT_PhysicalDisk or Get-PhysicalDIsk. (We're just using 0s for the serial number below.)

Using File Explorer, Robocopy or Xcopy to copy a large VHD to the virtual disk is not a recommended method to as this will result in slower than expected performance. The copy process does not go through the Storage Spaces Direct stack, which sits lower on the storage stack, and instead acts like a local copy process.

Spare Blocks Consumed Limit : Spare blocks consumed percentage limit reported by the device. When the Spare Blocks Consumed percentage for the device reaches this read-only value, Data ONTAP initiates a disk copy operation to prepare to remove the device from service. Omitted if value is unknown.

Disks that are not attached to a switch are named in the form : . . For disks with a LUN, the form is : . L . For instance, disk number 16 on host adapter 1a on a node named node0a is named node0a:1a.16. The same disk on LUN lun0 is named node0a:1a.16Llun0.

Disks that are attached to a switch are named in the form : : . . For disks with a LUN, the form is : : . L . For instance, disk number 08 on port 11 of switch fc1 on a node named node0a is named node0a:fc1:11.08. The same disk on LUN lun1 is named node0a:fc1:11.08Llun1.

Selects information about disks that are involved as either a source or destination of a copy operation, (due to either disk replacement or Rapid RAID Recovery) and that have the specified percentage of the copy operation completed.

Selects information about disks on paths that have incurred the specified number of errors. The value displayed is a measure of the health of a path expressed as a percentage of an error threshold. Once a path has reached or surpassed the error threshold, another path will be selected for I/O transfer, if there is one available.

I have multiple hard disks which get connected to my server and I'm not sure which one is what in the view of sdXY. If I could see the serial numbers of my hard disks from terminal, I could easily identify them.

As you can see, to lsblk, it thinks that an optical drive and floppy drive are also disks, which in a sense they are, though not really, since they don't become disks until a disk is inserted. And it shows nothing for serial, it also by the way shows nothing for other values, like label. Definitely a bug since this data is available to the system, that's where inxi gets it, direct.

Alternatively, once a repair vm is created, the changes can also be implemented by manually logging into the repair vm, mounting the attached copy of OS disk and making changes to its fstab file. Follow the steps here:

If both serial console and ALAR approach is not possible or fails , the repair has to be performed manually. Follow the steps here to manually attach the OS disk to a recovery VM and swap the OS disk back to the original VM:

If the output is different, then investigate and correct the problem. Degraded virtual drives usually indicate absent or failed physical disks. Replace critical disks and failed disks immediately. Otherwise, you risk data loss if the number of working disks in the server is less than the number required to sustain normal operation.

If a flash card fails, then the storage server software identifies the data in the flash cache by reading the data from the surviving mirror. It then writes the data to the server with the failed flash card. When the failure occurs, the software saves the location of the data lost in the failed flash cache. Resilvering then replaces the lost data with the mirrored copy. During resilvering, the grid disk status is ACTIVE -- RESILVERING WORKING.

When the server software detects a failure, it generates an alert that indicates that the flash disk, and the LUN on it, failed. The alert message includes the PCI slot number of the flash card and the exact FDOM number. These numbers uniquely identify the field replaceable unit (FRU). If you configured the system for alert notification, then the alert is sent to the designated address in an email message.

Each storage server maintains a copy of the software on the USB stick. Whenever the system configuration changes, the server updates the USB stick. You can use this USB stick to recover the server after a hardware replacement or a software failure. You restore the system when the system disks fail, the operating system has a corrupt file system, or the boot area is damaged. You can replace the disks, cards, CPU, memory, and so forth, and recover the server. You can insert the USB stick in a different server, and it will duplicate the old server.

With instances built on the Nitro System, EBS volumes are exposed as NVMe devices. You can use the Get-Disk command to map Windows disk numbers to EBS volume IDs. For more information, see Identify the EBS device.

In the diagram below, a command in Powershell lists some values regarding the above two USB devices. Clearly, what we have been calling the serial number does not conflate with what the identification in Powershell calls a serial number.

I tried the setup on a different computer we will call Computer 2. As if by magic, GSmartControl now showed me all of the correct information including serial number. Well now I have even bigger problems. Why would it work properly on Computer 2 but not Computer 1 What does the computer have to do with it

From the Windows NT-based (Windows XP and 7 specifically) command prompt, how can I get the serial number of a hard drive as a variable The one I'm looking at is the serial number of the physical hard disk drive

Sorry for a bit of a newbie question. I have a system with three identical SSD's (ie same model name, size, etc). I am backing up the disks using Clonezilla but wish to uniquely identify them. When they show up in Clonezilla, I see the three disks with unique names, and there seems to be a kind of a serial number identifier in Clonezilla at the end of the line when selecting the source disk.

This image is from a Clonezilla device-device tutorial where it gets to the step of choosing the SOURCE disk. What are those numbers that appear on the right. Will be something concrete that I can reference ie; Are those serial numbers on the right in that image

My thinking, absent any suggestion, is to start Clonezilla out in device-image mode where I'll be sure to recognize my source disk's swap partition in GB, jot down the numbers in the display (What ARE those numbers on the right anyway), control-C outta there, then cancel device-image mode. 1e1e36bf2d
