tape load count

[INCS Dept.]

Hi,

I am trying to get hold of some parameters to investigate when a tape drive is dirty. During this investigation I ran into info of tape drives which tell me about "tape load count". However, when I clean the drive, the tape load count is not resetted to 0.

Which parameters can I use to determine whether a tape drive is dirty and what values are used to determine this ?

Thanks,

INCS.

So what OS are you using, and what model is the tape drive?

If you have installed the Support Tools Bundle than you can use the cstm to check drive status.

eg

# cstm
cstm> map
....
9 0/0/2/0 PCI SCSI Interface (10000
10 0/0/2/0.2.0 SCSI Disk (SEAGATEST31820
11 0/0/2/1 PCI SCSI Interface (10000
12 0/0/2/1.0.0 SCSI Tape (HPC1537A) Information Successful
13 0/0/4/0 RS-232 Interface (103c104
14 0/0/5/0 RS-232 Interface (103c104
15 0/1 PCI Bus Adapter (782)
....

# as you can see my tape drive has the number 12
cstm> sel dev 12
cstm> info
cstm> il

# Now you see the "Drive Status" is "Good"

If you want it directly from the command line
you can do

# echo "sel dev 12; info; wait; il"|cstm |grep -i "Drive Status:"

The device can be differant from system to system. So check out first the device number.
