Operating Systems Solaris Hardware RAID on Solaris-10 disk Post 303046073 by MadeInGermany on Thursday 23rd of April 2020 01:50:56 AM

Thanks for the update.
These hardware RAIDs ship with their own software. I wonder if Solaris provides a general frontend where they can plug in. (Like fbconfig, it was a frontend command for most of the graphic adaptors.)

bio -- Block IO ioctl tunnel pseudo-device SYNOPSIS
pseudo-device bio DESCRIPTION
The bio driver provides userland applications ioctl(2) access to devices otherwise not found as /dev nodes. The /dev/bio device node oper- ates by delegating ioctl calls to a requested device driver. Only drivers which have registered with the bio device can be accessed via this interface. The following device drivers register with bio for volume management: arcmsr(4) Areca Technology Corporation SATA RAID controller cac(4) Compaq RAID array controller ciss(4) Compaq Smart ARRAY 5/6 SAS/SATA/SCSI RAID controller mfi(4) LSI Logic & Dell MegaRAID SAS RAID controller The following ioctl calls apply to the bio device: BIOCLOCATE Locate a named device and give back a cookie to the application for subsequent ioctl calls. The cookie is used to tunnel further ioctls to the right device. BIOCINQ Retrieve number of volumes and physical disks for a specific device. BIOCDISK Retrieve detailed information for the specified physical disk. Information returned can include status, size, channel, target, lun, vendor name, serial number, and processor device (ses). BIOCDISK_NOVOL Is just the same as BIOCDISK but doesn't require the disks to be in volume sets, so this applies to any physical disk con- nected to the controller. Note: this ioctl might not be supported on all hardware. BIOCVOL Retrieve detailed information for the specified volume. Information returned can include status, size, RAID level, number of disks, device name association (sd?) and vendor name. BIOCALARM Control the alarm beeper on the device. Supported states are: disable alarm, enable alarm, silence alarm, status and test alarm. Note: These options might not be supported on all hardware. BIOCBLINK Blink an LED of the specified physical disk. Supported blink states are: blink LED, unblink LED and blink alarm LED. Note: This option is only supported if the disk is governed by ses(4) and the hardware supports hardware blinking. BIOCSETSTATE Alter the state of specified physical disk. Supported states are: create/remove hot-spare, create/remove pass through disk, start/stop consistency check in a volume, online disk and offline disk. Note: These options might not be supported on all hardware. BIOCVOLOPS For operations in volume sets. It's able to create and remove a volume set in a supported RAID controller. Note: this ioctl might not be supported on all hardware. FILES
