Everyone, We have migrated a platform to a Centos 8 host using kvm guest machines Recently I tried to copy one of the guests to the external SD card on the back of the Dell R730xd, but I have not been able to get the Centos 8 host to recognize the SD card. I can use DRAC interface of the R730xd to see that the SD card is being recognized and the status of the external SD slot is turned from inactive to active when the card is inserted. I have used lsblk, fdisk -l, and 'dmesg | tail' none of which demonstrate that the Centos 8 host is recognizing the SD card. You help would be appreciated. Thanks !! -- Greg Ennis

Can you format it on that computer? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

In any case doesn't that need a vFlash card not a standard SD/SDHC card? From Wikipedia: https://en.wikipedia.org/wiki/Dell_DRAC To take advantage of storage greater than 256 MB on the iDRAC6 enterprise, Dell requires that a vFlash SD card be procured through Dell channels. As of December 2011, Dell vFlash SD cards differ from consumer SD cards by being over-provisioned by 100% for increased write endurance and performance.[21] While there are no other known functional differences between a Dell-branded vFlash SD card and a class 2 or greater SDHC card, the use of non-Dell media prevents the use of extended capacities and functions.
