You cannot mix SAS with SATA drives in the same VD / RAID Volume. As long as they support HotSwap and have the same bus like SAS or SATA. Also adding physical disks while running to a VD is working well. In our case, we have only one array, so functionally there is no difference. Re: Online Expand RAID 5 Array with MegaRAID Storage Manager It's no problem to expand online while OS is running. MegaRAID Storage Systems(SAS/SATA) are following systems.
A global hot spare can then be allocated to any array on the node. 1.1 MegaRAID Storage Manager MegaRAID Storage Manager (hereafter abbreviated for MSM) is an application that locally or remotely monitors and manages the MegaRAID Storage Systems(SAS/SATA). Hot spares can either be allocated to a specific array (when you have two or more), or it can be a "global" hot spare (GHS). In this way, the array returns to a fully operational state with minimal time in a degraded state. Try to connect the disk alone to another computer to see whether the problem is the disk, the cable or the. Try to reconnect the disk and/or reboot the server.

It seems that the controller can't talk properly to the disk (no serial number, no vendor or product. Roughly 30% of the disk performance is allocated for this background initialization.Ī "hot spare" is a drive physically in a node that is configured to automatically replace a drive that is in an array that fails. I think the problem is the capacity (0 Bytes). Until this is complete, disk performance will be degraded.
LSI MEGARAID STORAGE MANAGER EXPAND ARRAY FULL
This is because, after the initial initialization is complete, a full background initialization is performed. This drive group has 1 virtual drive, i want to add this new drive that is now showing as free capacity to. You will also note that the drives will have their activity LEDs blink for some time. Have a server with a LSI megaraid SAS 8704EM2, Turned it off and stuck a new drive in the front, I have gone into the BIOS via Ctrl+H at boot and the new drive shows, i have added it to an existing drive group, this took several hours.
