Many server vendors ship their servers with branded MegaRAID RAID controllers. The relationship I have with the many flavours they come in is sometimes a bit poluted I dare to saay.<\/p>\n
An excellent quick guide to the more modern StorCLI utility available to Linux, Windows, FreeBSD and others is Thomas Krenn's Wiki page on StorCLI<\/a>. More often than not I have to look up in the CLI reference made available by (today) Broadcom.<\/p>\n Now I've come across a slightly stubborn controller that reported a Virtual Drive not being consistent. <\/p>\n I've come across a system with an IBM-branded MegaRAID controller where one of the virtual disks (a RAID5) show an optimal state but not consistent. CLI Version = 007.0409.0000.0000 Nov 06, 2017 Product Name = ServeRAID M5110 [...]<\/p>\n VD LIST : --------------------------------------------------------------- I've attempted to start a consistency check on that VD but the controller always reported it couldn't:<\/p>\n At first I suspected a running patrol read would block it. (storcli64 \/c0 show pr) but the consistency check wouldn't start afterwards either. In the end after trying to resume it it was finally OK:<\/p>\n # \/opt\/MegaRAID\/storcli\/storcli64 \/c0 \/v1 resume cc Afterwards the consistency check quickly ended as done and the alert issued by the monitoring system got cleared. Nonetheless I manually started a consistency check in order to see if any issues would be found. I guess the consistency check was paused at some point in time due to a preceeding firmware updated but wasn't restarted automatically afterwards.<\/p>\n","protected":false},"excerpt":{"rendered":" Many server vendors ship their servers with branded MegaRAID RAID controllers.
