What's the safest way to swap an SSD (RAID 10)?

cn flag

I have machines (4x 2 TB SSDs, Hardware RAID 10 via LSI 9265-8i cards) and occasionally need to swap an SSD - for example if it fails.

I'm curious to hear what people consider to be the safest approach in swapping failed drives whilst a server is online and booted into the OS.

One thing that unfortunately won't work is enabling drive LED (megali PdLocate) for the good drives (leaving the bad drive without a light, and the obvious one to replace). The SuperMicro casing seems to mean these aren't visible.

If the server is setup for RAID 10 with "Hotswap" (Meaning it has a back plane for quick HDD removal) you should be able to safely remove at least one of the drives at at all times unless the array is rebuilding. A properly built server will usually have the Port 0(Drive 1) HDD on the left and port 3 (Drive 4) on the right, that is one way to identify. Either way when you figure it out make sure to label as such.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
