The best way to think about it... "replace" allows you to control which spare disk is used when replacing the active (failing) disk. "fail" selects any available matching spare (we're assuming you have one available). If you don't mind using an existing spare to start replacing the first failing disk, then just start serially "replacing", removing bad drive, inserting new drive (and ensuring it gets assigned and become spare). If you really want to replace all three bad drives with your new replacements, you'll need to swap an existing spare with one of your shiny new drives, first - then use "replace".

Not only is stack #2 your best option, it's your only option. Mixing IOM6 and IOM12 shelves on the same stack is unsupported.

I'm not sure what your statement "Tried allready - no effort." was referring to... Similar to Alex's comment, I would simplify the test. If HA, pull the partner node (assuming it's not serving data - take downtime). Leave it out. Pull the problem PCM out. Leave it out. Shut off/disconnect the PSUs to the chassis. Leave them off for at least 1 minute. Power up the PSU's. With the console port connected, insert the problem PCM (remember, the HA partner PCM should still be removed). Check console output. Wait about a minute - the try "sp status" from LOADER to see if the SP is responsive. Try Ctrl-G to switch over the SP to see if it's responsive. If SP remains unresponsive, the PCM would need to be replaced.

While connected to console, press "Ctrl-G" to switch to the SP console. "Ctrl-D" to return to the ONTAP/LOADER console.

Dmitry,karpal516, karpal518. There is no alternative drive part. NetApp drive models can only be replaced with the same NetApp drive model. What is the problem you are trying to solve?

andris · ‎2019-08-06

It sure looks like the SP is nonresponsive. If you press "Ctrl-G" at the console, it switches over to the SP CLI prompt. Can you get a response? A simple resolution would be to fully power cycle the controller/chassis or just pull the PCM out for a minute -- then re-insert it. Monitor the console for what happens after re-insertion. If nothing changes, looks like the controller is toast.

If you want to use GUI-based setup, you can use System Setup 3.1 if you're going with 8.2.5P3 7-Mode. If you're going with ONTAP 9.1P19, you can use the OnCommand System Manager web interface.

Assuming: 1. Your FAS2220 still has NetApp Support entitlement and you have access top ONTAP software 2. You don't care about any existing data I would just initialize the system and upgrade to Data ONTAP 8.2.5P3 (if you're sticking with 7-Mode). KB: How to re-initialize / re-install / 4a Data ONTAP on a NetApp controller If you really want to squeeze the best out of the FAS2220 in terms of storage efficiency, consider leaving 7-Mode behind and going to ONTAP 9.1P19 (ONTAP 9.1 is the terminal ONTAP release for FAS22xx). You can follow this KB for instructions (it's a bit complicated): KB: How to repurpose a Data ONTAP 8.1.x or later 7-Mode node to a clustered Data ONTAP 8.3 node

Good info from Alex. It's also a great idea to check system configuration/health with Active IQ Config Advisor (a downloadable tool from the NetApp Support site). See: https://mysupport.netapp.com/tools/info/ECMS1357843I.html?productID=61923&pcfContentID=ECMS1357843

Being a SnapMirror destination doesn't have any bearing on the disk maintenance/recovery activity, IMO. The disks are just getting older... the activity you described is considered "normal" care and feeding by ONTAP of the storage subsystem. If the errors start becoming more frequent or you start seeing HDD read/write latencies above the norm, then that's worthy of a closer look and a support case. BTW, 8.3.x ONTAP has passed End-of-Version Support. You need to upgrade to 9.1, 9.3 or 9.5 to stay in a supported configuration, soon.

Please read this document section: https://docs.netapp.com/ontap-9/topic/com.netapp.doc.dot-cm-psmg/GUID-4D43889E-7200-46D3-8182-A6AD836FE317.html Specifically: How hot spare disks work A hot spare disk is a disk that is assigned to a storage system and is ready for use, but is not in use by a RAID group and does not hold any data. How low spare warnings can help you manage your spare disks By default, warnings are issued to the console and logs if you have fewer than one hot spare drive that matches the attributes of each drive in your storage system. You can change the threshold value for these warning messages to ensure that your system adheres to best practices.

To recap: Entry-level FAS systems (with HDDs) will only perform ADP on the internal/embedded drives. AFF systems will use ADP on up to 48 SSDs across multiple shelves. However, for AFF-A220/A220, you will typically see ADP on the 24 internal SSDs only because NetApp Mfg. initializes the system without any add-on storage. 12-drive entry-level FAS systems (FAS2520, 2620, 2720) with HDD sizes that require RAID-TEC need to be explicitly set RAID-TEC to "false" for internal drive ADP (i.e. LOADER> setenv bootarg.raid.allow-raid-tec? false) to ensure that ADP will use 3d+2p+1s P1 partitions for each node. Important: Once you have initialized the system, set this bootarg back to true so that any additional large-HDD RG's use TEC for optimal protection. If the entry-level FAS system does not contain any internal drives, ADP will use external storage.

Important: Once you have initialized the system, set this bootarg back to true so that any additional large-HDD RG's use TEC for optimal protection. As you noted, if you expand a RG with partitions, spare whole disks will be automatically partitioned. That said, you would avoid the wasted P1 partition "tax" if you simply created a new RG with your external shelf drives as whole disks.

No.

By "flash cache", I assume you actually mean "flash pools" - SSD's used in hybrid aggregates? As others have mentioned, determine the SSD model number and shelf model to look up in HWU and compare between your old and new systems. If the shelves are the same, there's no reason why they can't be repurposed. Just one caveat: SSD's have a finite rated life. SSD's used in flash pools are written heavily and you may find that the rated life is too high to consider repurposing (it ranges between 0% and 100%). Do not use an SSD with a rated life approaching 100%. > store show disk -a (in 7-Mode/nodeshell).

+1. With the limited number of drives involved, you're probably looking at an active/passive configuration to maximize the amount of available storage. See: http://docs.netapp.com/ontap-9/topic/com.netapp.doc.dot-cm-psmg/GUID-4AC35094-4077-4F1E-8D6E-82BF111354B0.html

What ONTAP version are you running? The more recent the version, the more likely you won't see any hiccups with a switch reboot and the subsequent LIF failovers. This handy command will show you the connection info from CDP (neighbor discovery). ::> network device-discovery show

It’s far too old for there to be any official download location at NetApp. You’re only hope is to find it squirreled away on the Internet, somewhere... or someone on the community still happens to have a copy.

Yes, they can be used as data LIFs/ports. HWU lists all of the cluster port options available for a given platform. Eg. 10GBASE-T can be used for TNSC.

Envision your 3 shelves as a stack. Always connect circles to squares. One controller SAS port connects to the top of the stack on the A side of the IOMs; one SAS port connects to the bottom of the stack on the B side of the IOMs. Daisy-chain between the shelves on both the A and B sides.

Config Advisor is a great idea - a wonderful tool to use any time you install or change things on a FAS/AFF system. https://mysupport.netapp.com/tools/info/ECMS1357843I.html?productID=61923&pcfContentID=ECMS1357843

Power cycle that PCM (i.e. pull it out, wait a minute, put it back in). If the ethernet ports still don't show up, you have a hardware issue.
