Finding physical location of a disk


Finding physical location of a disk
When you would like to replace disk (or so) you need to know its physical location.
In this example I'm going to find the physical location of disk hdisk1:
# prtconf | grep '+ hdisk1'
+ hdisk1           U0.1-P2/Z1-A9     16 Bit LVD SCSI Disk Drive (18200 MB)
We now know that the location is U0.1-P2/Z1-A9. Now we can let the system blink a light for that disk. For that, start diag:
  • # diag
  • select "Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.)"
  • select "Identify and Attention Indicators"
  • select your disk, in this example "U0.1-P2/Z1-A9"
  • press enter, a '+' will be displayed
  • press F7 to switch on the light; the '+' will be replaced with an 'I'
Disabling the light:
  • press enter on the selected disk ("U0.1-P2/Z1-A9"), the 'I' will be replaced with a '+'
  • press F7: the '+' will be removed and the light is disabled
