How to replace failed hard drive on NetApp FAS

How to replace failed hard drive on NetApp FAS

What:

NetApp FAS270, FAS2020, FAS2040, FAS2240, FAS2050

Problem:

Hard drive has failed and needs replacement.

Solution:

Disk will have an amber LED on the front of it if it has an issue. You will need a disk of the same capacity as the one you are removing or larger, also make sure disk is the correct type for the shelves that you have.
You can identify failed disks by logging onto the controllers command line via SSH and running the following command:

aggr status -f

-f will identify any of the broken disks.
Output should give you a <disk id> i.e. 0c.00.10

If the LED is not lit in which some cases this can happen, you can illuminate it.

SSH onto the NetApp box and logon (if you haven’t done it already) and switch to advanced mode.

priv set advanced
led_on <disk id identified above>
led_off <disk id identified above>
priv set

Alternatively you can use blink_on & blink_off instead of led_on & led_off.

Remove drive from the shelf and wait for 60 seconds before inserting a new one.

When new drive is in place run the following command to check whether the ID of the disk you have just fitted is owned or not.

disk show -n

If disk auto assign is enabled it’ll be assigned to the head which had the failed disk, if not you will have to do it manually.

disk assign <disk id>

If it won’t accept the command, it might have been auto assigned to the wrong controller/system.  You can clear the assignment from the disk using the following command then try again.

disk assign <disk id> -s unowned -f

The replaced disk will now be assigned as a spare disk to replace the spare which was used when the original failed.
You can check Status of this using following command:

aggr status -s

To check auto disk assign feature use:

options disk auto_assign

The output will either show on or off.

Using CheckSUR and fix Corruption

These are just notes for myself. I will rewrite this article when i get to the bottom of the issue i’m fixing.

Using CheckSUR and update packages to fix corruption

How to extract msu/msp/msi/exe files from the command line

I find these commands quite helpful — maybe you know them already — if not, here you go:

Microsoft Hotfix Installer (.exe)

setup.exe /t:C:<target_dir> /c

Microsoft Update Standalone Package (.msu)

expand -F:* update.msu C:<target_dir>
cd <target_dir>
expand -F:* update.cab C:<target_dir>

Microsoft Patch File (.msp)

msix patch.msp /out C:<target_dir>
msix.zip

Windows Installer Package (.msi)

msiexec /a setup.msi /qb TARGETDIR=C:<target_dir>

Exchange 2010 The mailbox dumpster size exceeds the target quota

Moving some customers mail boxes around i kept getting a error about dumpster size exceeding the target quota.I couldn’t find much info on it. But this seems to fix it.
1.) Give your account rights to open the mailbox.
2.) Go to control panel > mail > profiles > ask for a profile each time outlook opens
3.) Open Outlook > New profile > input appropriate info for mailbox and users alias > UNCHECK “cached exchange mode” > open the users mailbox once w/ Outlook, then close Outlook.
4.) Open MFCMapi (if Outlook is x64, then use x64 of MFCMapi)
5.) ok > Session > Logon and display store table
6.) Select the profile for the user you added.
7.) Double click “mailbox – user”
8.) Expand “Root Container” > right click on “Recoverable Items” and select > open contents table
9.) Give it a min to enumerate all items
10.) Select any unwanted items and right click “delete message”
11.) You can also expand recoverable items and then highlight purge or deletions and open the contents table for those as well.
12.) Then close windows until you get the original one and logoff.
Be careful with MFCMapi as it can cause serious damage to a mailbox.

Windows 10 Bootrec – the requested system device cannot be found

After cloning a SSD for a customer it wouldn’t boot after running the normal

Bootrec /fixmbr
Bootrec /fixboot
Bootrec /scanos
Bootrec /rebuildbcd
But the Bootrec /rebuildbcd wouldn’t work with a error  “The requested system device cannot be found”

after spending time looking in to this issue i found a  forum post that fixed it right up.

Firstly, boot from a UEFI Windows 8/10 recovery disk (CD/DVD/USB) – I found that the automated recovery process didn’t find the correct Windows partition, nor when I managed to add it to BCD settings would it make it reliably bootable e.g. using BCDEDIT I got it to find and launch the Windows partition but it refused to cold boot or would not “keep” the settings after a 2nd reboot or power off.

Go into the Advanced options and run the Command Prompt.

Enter diskpart to use the DiskPart tool to ensure you have all the right partitions and to identify your EFI partition – the key thing here is that your EFI partition is formatted as FAT32:

DISKPART> sel disk 0

Disk 0 is now the selected disk.

DISKPART> list vol

  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     E                       DVD-ROM         0 B  No Media
  Volume 1     C                NTFS   Partition    195 GB  Healthy    Boot
  Volume 2         WINRE        NTFS   Partition    400 MB  Healthy    Hidden
  Volume 3                      FAT32  Partition    260 MB  Healthy    System

Then assign a drive letter to the EFI partition:

DISKPART> sel vol 3

Volume 3 is the selected volume.

DISKPART> assign letter=b:

DiskPart successfully assigned the drive letter or mount point.

Exit DiskPart tool by entering exit and at the command prompt run the following:

cd /d b:\EFI\Microsoft\Boot\

bootrec /fixboot

Delete or rename the BCD file:

ren BCD BCD.bak

Use bcdboot.exe to recreate BCD store:

bcdboot c:\Windows /l en-gb /s b: /f ALL

The /f ALL parameter updates the BIOS settings including UEFI firmware/NVRAM, /l en-gb is to localise for UK/GB locale. The localisation defaults to US English, or use en-US.

Reboot and cross your fingers.

Clear Mailcleaner Incomming Que

If you need to clean out the incoming que from the mail cleaner que try the command below in the SSH.

 

If you want to test first run

/opt/exim4/bin/exiqgrep -C /usr/mailcleaner/etc/exim/exim_stage1.conf domain.tld

If that shows the emails that you want to remove try

/opt/exim4/bin/exiqgrep -C /usr/mailcleaner/etc/exim/exim_stage1.conf -i domain.tld | xargs /opt/exim4/bin/exim -C /usr/mailcleaner/etc/exim/exim_stage1.conf -Mrm

Website Panel Error when adding Exchange Mail Box

After updating to Web Site Panel 2.1 i had a error creating exchange mail boxes on some customers. I got a error like this in the event viewer.

System.Web.Services.Protocols.SoapException: Server was unable to process request. —> System.NullReferenceException: Object reference not set to an instance of an object.
at WebsitePanel.EnterpriseServer.ExchangeServerController.GetMailboxSetupInstructions(Int32 itemId, Int32 accountId, Boolean pmm, Boolean emailMode, Boolean signup, String passwordResetUrl)
at WebsitePanel.EnterpriseServer.esExchangeServer.GetMailboxSetupInstructions(Int32 itemId, Int32 accountId, Boolean pmm, Boolean emailMode, Boolean signup, String passwordResetUrl)

 

Turns out the fix is simple. In the User account details for the space change the Mail Format Setting from TEXT to HTML. and it solves the issue….. not sure why but its fixed.
