Dear, We have 1 Eseries E2812 with 18 Disk of 4TB and 1 DDP we must replace disk of 4 TB by disk of 12TB. we have 12 Disk disks on 4TB on shelf ID99 and 6 disks of 4 TB on shelf ID01 slot 0 to 5. and free slot 6 to 11. - Adding 6 New Disk in Shelf ID 01 Slot 6 to 11 - Extend DDP with theses 6 Disk - We will have a warning " adding disk of 12 TB with Disk of 4TB" If you must add unassigned drives with a larger capacity, be aware that the usable capacity of the unassigned drives that you add is reduced so that they match the current capacities of the drives in the pool or volume group. (we will lose 8 TB on each new disk) . - Rebalancing of Aggregate DDP. - Decrease DDP by removing 6 disks of 4TB shelf ID99 slot 0 to 5. - Replace Physical disk 4TB by 12 TB shelf ID99 slot 0 to 5 - Increase DDP with 6 new disks of 12TB - We will have a warning " adding disk of 12 TB with Disk of 4TB" we will loses 8 TB on each new disk. - Rebalancing of Aggregate DDP. - Decrease DDP by removing 6 disks of 4TB shelf ID99 slot 6 to 11. - Replace Physical disk 4TB by 12 TB shelf ID99 slot 6 to 11. - Increase DDP with 6 new disks of 12TB - Rebalancing of Aggregate DDP. - Decrease DDP by removing 6 disks of 4TB shelf ID01 slot 0 to 5. - Replace Physical disk 4TB by 12 TB shelf ID01 slot 0 to 5. - Increase DDP with 6 new disks of 12TB - Rebalancing of Aggregate DDP. - at this moment we don’t have disk 4 TB in Pool DDP we will have just 24 disks of 12 TB - I would like saw if is possible to retrieve full capacity of disk 12 TB on Aggregate DPP. Thanks in advance

Server has ThinkSystem Broadcom 57454 10GBASE-T 4-port PCIe Ethernet Adapter and we would like to connect it directly without 10Gb switch with Netapp E2824 storage. Can't find in documentation this is supported so I wanted to ask here. Anybody with this kind of setup?

Hi All, we have a SANtricity Storage of Version 11.25 on top of it, we have disk pool 1 created with help of 48 drive. Recently we received an alert of 1 disk failed . So, I have below query like, 1) if i remove failed disk from pool and will that pool recreate with 47 disk/drive. 2) do i need run any command to remove failed disk before remove. 3) how can I recreate a pool with 47 Disk( is this make any data loss). Please suggest your opinion. Thank you, Rahul Gabhane

Hello People Customer wants to use SAS ports to be able to export a volume to HP machines in Direct Attach. What is the best practice? How do I enable the SAS protocol? What is the best configuration? DDP or RAID6? Thank's in advance Alessandro

Hi, we have a controller pair (out of support since EoApril, unfortunately) which went into an LJ lockdown. AFAICS that comes from a logical failure of the Config Database. That condition started in timely vicinity of a disk replacement. The storage is organized in disk pools ("declustered arrays"). I did not notify the issue immediately as I was replacing more disks in other storage systems. I do also not completely recall whether the LJ lockdown was the initial state after the failure set on; I realized it only after resetting the controllers. However, they were unreachable via their admin IFs before the reset. The meaning of the LJ code is "The controller has insufficient memory to support the current configuration". We tried resetting the system in different variants (resetting one controller while the other kept running, resetting one controller with the respective other one removed, all with the newly inserted disk in or removed, respectively. We also tried running lemClearLockdown. The controllers always run into the same lockdown. I suspect the database has gotten some (invalid) entry which confuses the CRUSH setup, which can also be derived from the boot messages visible at the serial console which include: 05/25/22-11:53:06 (tRAID): WARN: Error threshold exceeded: "Client_Crush_Invalid_Memory_Config" 05/25/22-11:53:06 (tRAID): WARN: LEM:Client threshold Exceeded 05/25/22-11:53:06 (tRAID): NOTE: LEM: checkError(); Error threshold exceeded;SUSPENDED_LOCKDOWN; 05/25/22-11:53:06 (tRAID): WARN: sodLockdownCheck: sodSequence update: SuspLockdown 05/25/22-11:53:06 (tRAID): NOTE: Inter-Controller Communication Channels Opened 05/25/22-11:53:06 (tRAID): WARN: Error threshold exceeded: "Client_Crush_Invalid_Memory_Config" 05/25/22-11:53:06 (tRAID): WARN: Client reported lockdown: "Client_Crush_Invalid_Memory_Config" 05/25/22-11:53:06 (tRAID): NOTE: Flashing tray summary fault LED The memory of the controllers has of course not been changed by us. While we do have data backups, the controller pair contributes to the storage of file systems with about 11 PB, and if ever possible we would not want to restore from tape as that would probably take very long. We'd rather want to fix the supposed issue with the database. We found stored database exports from both controllers which were very likely initiated by the StorageManager (located in /var/opt/SM/monitor/dbcapture/, last ones from Jan 12 this year). I have to find out whether disks were replaced after that; if not (except for the recent one) I hope removing that lastly installed disk and replaying the config from January could do the trick. However, I do not know how to transfer and activate an exported database dump via the serial line. If there are other/better ways to overcome our problem, I'd be glad to learn about them. BTW: we are also trying to get Netapp involved, but as we purchased these systems as OEM we are not yet there. Sincerely ufa
