Hi, I am working on SCSI hotplugging on opensolaris and testing the system to replace a disk/remove a disk/add a disk without rebooting the system to recognize the newly added disks/removed disks. I am using the cfgadm tool which supports hotplugging, this is an administration tool available on solaris >= 7 which is used to perform the above operations on SCSI bus. drvconfig on Solaris 2.6-2.8 only sees disks which are added dynamically, but doesn't recognize the disk being removed. I am getting an error when I wanted to remove a disk from a SCSI bus, by using the following command:- # cfgadm -x remove_device c1::dsk/c1t1d0 Removing SCSI device: /devices/p...@1f,0/p...@1/s...@1,1/s...@1,0 This operation will suspend activity on SCSI bus: c1 continue: (yes/no)? y cfgadm: Hardware specific failure: SCSI bus quiesce failed : I/O error
Some administrators might have used this, so just thought to check with you all. if anybody is familiar with this tool or any other tool which supports hotplugging, please let me know. thanks
