How to determine a verion of a kernel driver

[Tony Williams]

How can I dtermine what version of the stape driver is loaded in the kernel?

Thanks

Somebody who better understands the kernel internals can correct me if I am wrong

This is what I figured.

Most of the kernel drivers object files are "archived" in to one archive file called libhp-ux.a.

This file is located in /usr/lib/conf/ directory and ar command can be used to manipulate this file.

# ar -t /usr/lib/conf/libhp-ux.a

this will list all the files in there

# ar -x /usr/lib/conf/libhp-ux.a scsi_tape.o

# what scsi_tape.o

This will tell you the version of stape.

Again, this is the understanding I developed by digging in the system. Possible that I am wrong :-)

Hi Tony,

If you're running 11i v2, there is a new command called "kcmodule" that may tell you what you want a little easier. This command displays information about kernel modules, of which stape is one. On my 11.23 system (i.e. 11i v2), I get:

# kcmodule -v stape
Module stape [3F56E2F0]
Description SCSI Tape Driver
State unused
State at Next Boot unused
Capable static unused
Depends On module sctl:0.0.0
interface HPUX_11_23:1.0

Don't know if this is what you're looking for, but thought I'd mention it for those people unfamiliar with kcmodules.

Regards,

Dave

Wow, thanks for the info it was very good. You probably meant the directory is /usr/conf/lib. We are using 11.23 so when I looked into the file using your commands there was no stape in it.

/usr/conf/lib>ar -t /usr/conf/lib/libhp-ux.a
softintr.o
param.o
libhp_ux.modmeta.o
netfunc.o
strtio_tunables_default.o
lv_default.o
lv_config.o
nfs_iface.o
domainname.o
libhp-ux_vers.o

I dont believe there is no direct relation between the object files and the driver name.

I believe scsi_tape.o is the object file for the stape driver.

[Sundar_7]

Yes, sorry I intended to mention directory /usr/conf/lib, not /usr/lib/conf

[Sundar_7]

I figured you dont even have to extract the .o file using ar to find out the version

# what /usr/conf/lib/libhp-ux.a | grep tape

Look for scsi_tape.o
