Solaris's Hanging Disk experience

A few days ago the company bought a 146G 68-pin SCSI external disk (for backup) and encountered a problem while hanging the disk.

1. The target number of the new disk is 5, the blade2000 machine to be hooked has a 72G built-in disk and two external disks with 146G respectively (T is: 3 and 4,vfstab corresponding two external disks are: C2T0D0S6 and C2T1D0S6).

2. After Boot-r, the system always reports: Reset SCSI bus,configuring failure. I switched the wiring position and it doesn't work. The same is true with CD-ROM starting. A new disk could not be found with the format command. Later, I hook up a new disk alone, also reported: Reset SCSI Bus, with the format command can not find a new disk.

3. I put the new disk on another blade2000 (this machine has only a 72G of built-in disk), this time there is no special hint, after entering the system, I used the format command to see the built-in disk, but also see 146G disk, I chose the 146G option 5, C2T5D0S2---label----newfs/dev/rdsk/c2t5d0s2 carriage return, it starts a row of digits in a row of numbers, and after about a few minutes, it's done. I added a line to the Vfstab, and the hang point is home2. After the reboot, the system hangs on the disk, and I see it with the Df-k command.

At this point, I conclude that the new disk itself is not a problem, may be where I set up improper cause. So I put the new disk on the blade2000 for backup, this time it appeared: wanring:/pci@8,700000/scsi26,1 (GLM1)

Disconnected command timeout for Target 5.0

Got SCSI bus Reset

4. I took the new disk to the blade2000, and (before that, I restored the line on the commented Vfstab), but the system could not find the disk (during the start-up: no such device).

At this time, I suspect that the cable is a problem, so look at both ends of the interface, fruit otherwise, at one end of the mouth, there is a root cuttings needle pressure crooked, I carefully will it to the right, plug the cable, boot, all OK.

Experience: When inserting cable, must be fuzheng, force evenly, careful. The cable pins of the SCSI disk are much softer than the coaxial printer cable pins.
