HPUX/Suse Cross Reference? Where is rmsf?

Craig Johnson_1 — Wed, 30 May 2007 09:09:20 GMT

Is there a Linux equivalent to HP's "rmsf" command (and it's contemporaries)? I'm running SLES9.

There is no rmsf equivalent in Linux. Most devices are managed dinamically. What do you need to do?

We are trying to clean up after moving EMC BCV's to another cluster. What happens after you do this is that commands such as vgs report problems - problems we'd rather not see, because they break our automation.

If your problem is with volume groups reports, use the vgexport command to remove the volume groups configuration from the system.

Hi Craiq,

since you have SLES9 have a look at
/bin/rescan-scsi-bus.sh
from
# rpm -qf /bin/rescan-scsi-bus.sh
scsi-1.7_2.36_1.16_0.11-0.4

maybe you have to adjust some
'seq 0 7' expressions to scan a wider range.

These are not on a SCSI bus, they are SAN attached disks (fiber channel). I'm not sure what that bus scan is going to buy me?

Hi Craig,

it doesnt matter if it is "real" SCSI or fibre channel. Fibre is just the "transport medium" for SCSI-commands.

With output of lsscsi/inq.linux and
rescan-scsi-bus.sh you can selectivly delete
some DSFs.

Re: HPUX/Suse Cross Reference? Where is rmsf?

Craig Johnson_1 — Thu, 31 May 2007 09:09:53 GMT

OK, thanks everyone. Now, what is the difference between rmsf and just good old rm?

Re: HPUX/Suse Cross Reference? Where is rmsf?

Heironimus — Thu, 31 May 2007 10:09:11 GMT

insf/rmsf can also manipulate HP-UX's list of currently-active devices, as well as operate on HP hardware paths and entire device classes. rm just removes files on the filesystem.

Re: HPUX/Suse Cross Reference? Where is rmsf?

Craig Johnson_1 — Thu, 31 May 2007 10:46:45 GMT

Yet there is no equivalent in SLES?

Re: HPUX/Suse Cross Reference? Where is rmsf?

Heironimus — Thu, 31 May 2007 16:28:34 GMT

There is no equivalent because Linux doesn't manage devices and drivers the same way that HP-UX does. If the only thing you need is to change files out under /dev, you can use the MAKEDEV script to create them and rm to remove them. If you need to do any of the other things that insf/rmsf/etc do then you'll have a different procedure to follow.

Since the "open failed" messages look like they're devices from EMC's multipath software, you should probably make sure that there isn't any special EMC procedure before you manually remove device files.

it looks like there were some EMC disk whihc were present earlier is not visible now.

What is the linux verison? whihc EMC s/w do u use to manage the emc disk, like power path?. Did u reinstall it ?
