HBA/RAID Utilities
Contents
Adaptec RAID integration
Adaptec controllers are automatically detected and can be managed via the QuantaStor web management interface.
Fusion IO integration
The Fusion IO integration requires that the fio-util and iomemory-vsl packages are installed. Once installed the Fusion IO control and logic devices will automatically show up in the Hardware Enclosures & Controllers view within QuantaStor Manager.
LSI 3ware integration
3ware controllers are automatically discovered and can be managed via the QuantaStor web management interface.
Note that if you arbitrarily remove a disk that was being utilized by a 3ware RAID unit, there are additional steps required before you can re-add it to the appliance. 3ware writes configuration data on the disk in what's called a Disk Control Block (DCB) and this needs to be scrubbed before you can use the disk again as a hot spare or within another unit. There is a great article written here on how to scrub the DCB on a disk so that you can use it again with your LSI 3ware controller. Formatting the disk in another system will also suffice. You can then add it back into the old system and designate it as a spare, and if you have a unit that is degraded it will automatically adopt the spare and begin rebuilding the unit back to a fully fault tolerant status. Of course if you pulled the disk because it was faulty you'll want RMA it to the manufacture for a warranty replacement.
LSI MegaRAID / DELL PERC integration
LSI MegaRAID, DELL PERC, IBM ServeRAID and Intel RAID controllers are fully supported by QuantaStor and can be managed via the web management interface. Note also that QuantaStor includes a command line utility called qs-util which assists with some MegaRAID maintenance operations. These include:
qs-util megawb : Set Write-Back cache mode on all LSI MR units w/ BBU
qs-util megaforcewb : (W!) Force Write-Back cache mode on all LSI MR units
qs-util megaclearforeign : (W!) Clear the foreign config info from all LSI controllers
qs-util megaccsetup : Setup MegaRAID consistency check and patrol read settings
qs-util megalsiget : Generates a LSIget log report and sends it to support@osnexus.com
