s
sss(1M) sss(1M)
attempts to obtain exclusive access to the disk array. If the disk array is already opened by another
process (for example, LVM — the Logical Volume Manager), a ‘‘device busy’’ error message is
returned by the driver. To eliminate the ‘‘device busy’’ condition, determine what process has the
device open. In the case of LVM, it is necessary to deactivate the volume group containing the array
before configuring the spindle sync state of the drives in the array (see vgchange(1M)).
sss: LUN # too big
The LUN number, which is derived from the device file name, is out of range.
sss: Not a raw file
sss
must be able to open the device file for raw access.
sss: Not an HP SCSI disk array
The device being addressed is not an HP SCSI disk array.
sss: Transfer length error
The amount of data actually sent to or received from the device was not the expected amount.
SCSI (device level) communication errors:
Sense data associated with the failed operation is printed.
Error messages generated by system calls:
sss uses the following system calls:
malloc(), free(), stat(), open(), close(), read(), write(), and ioctl().
Documentation for these HP-UX system calls contains information about the specific error conditions asso-
ciated with each call.
sss does not alter the value of errno. The interpretation of
errno for printing
purposes is performed by the system utility
strerror().
EXAMPLES
To display the spindle synchronization status of drives on HP SCSI disk array
/dev/rdsk/c22d0s2 on
a Series 800:
sss -d /dev/rdsk/c22d0s2
To enable spindle synchronization on all drives of the HP SCSI disk array
/dev/rdsk/c410d3l3s0 on
a Series 700:
sss -on /dev/rdsk/c410d3l3s0
The drive on SCSI channel 3 at SCSI ID 0 of the HP SCSI disk array /dev/rdsk/c410d3l3s0
has
just been replaced. The other drives in the array are synchronized, and the replaced one was a slave. To
enable spindle synchronization on the new drive on a Series 700:
sss -on -s c3i0 /dev/rdsk/c410d3l3s0
If, in the replacement scenario above, the replaced drive was the master, to enable spindle synchronization
and make the new drive a master:
sss -on c3i0 /dev/rdsk/c410d3l3s0
or, alternatively, enable the whole set again:
sss -on /dev/rdsk/c410d3l3s0
DEPENDENCIES
This utility is currently supported only on HP C2425, HP C2427, and HP C2430 disk arrays.
