There is a problem with the hot-swap SAS drives.
Initial data: Nexenta 4.0.2 Server-based Supermicro (MB S5520HC, internal RAID controller RMS2LL080/LSI 2008), 12 HDD SAS 300G 10 HDD SATA 1T, 2 SSD 160G.
Disks are divided into three pools:
- System SAS 2x300 mirror
- "fast" array of SAS drives 10 (9 + 1 spare)
- "slow" SATA array 10 drives
At some point, out of order, two SAS drives:

Next, make a replacement procedure zpool offline / detach and cfgadm -c unconfigure for each disk. After installing one drive (in this case, syspool) in the logs can see the following:

If we assume that the new drive is also defective and put others get even more strange picture. The logs installation disk does not appear at all. But the information is displayed on the withdrawal of the disc:
Oct 13 14:50:26 nxstor scsi: [ID 107833 kern.notice] /pci@0,0/pci8086,3a40@1c/pci8086,350e@0 (mpt_sas0):
Oct 13 14:50:26 nxstor PhysDiskNum 2 with DevHandle 0x23 in slot 0 for enclosure with handle 0x0 is now offline
Empirically, it has been found that the problem only applies to SAS drives. This in turn has suggested about the problem in the cfgadm with MPxIO driver and mpt_sas (turns out this is a known problem solaris and wrote that she was resolved, but it is not clear whether it is passed in opensolaris).
What to do next? Who ever encountered a similar problem?
