Not able to execute commands......

subodhbagade — Fri, 19 Feb 2010 11:51:24 GMT

Hi ,

I am having HP-UX B.11.00 U PA-RISC system,

I am facing following issues,

(1)Not able to execute # vgdisplay , #ioscan …. I have also tried with giving its entire path “ /usr/sbin “ but not giving any o/p…..But I can execute #bdf cmd

(2) when I am trying to execute # /usr/sbin/sam it giving me following msg

(a) Superuser(root) does not belong to group "sys". Proceeding with SAM │
│ when superuser(root) does not belong to group "sys" will result in │
│ files and directories getting created with a wrong group ID. Do you │
│ want to change the group to "sys" and continue?
(b) If I continue . then ….

Superuser's(root) group successfully changed from group "users" with │
│ GID "20" to group "sys" with GID "3"

(c) Giving me error

The command, pd_ioparser, has failed while trying to retrieve
information about the device class, CTL. The stderr output from the
command was:-------

(3) This is o/p of my passwd file

root:pWLMcyBm77Gyk:0:3::/:/sbin/sh

and /etc/group is

root::0:root
sys::3:root,uucp

(4) I have installed the sudo-1.7.2 utility from http://www.gratisoft.us/sudo/install.html

I went to source dir , ran ./configure script and then “ make install … I can see visudo and sudoers file but it is not showing in /var/adm/sw/product database …

Please let me know , can we correlate this issue with sudo installation and if yes how I can remove it as I am not able to execute #swremove

Thank in advance!!!!

Regards,
Subodh.

Hi:

See if you can (as root) run:

# swverify \*

This will take some time but will read the IPD ('/var/adm/sw') database and match the expected permisssions, ownerships and modification times of its objects with the actual files and directories.

I'm not sure that your 'sudo' package even uses the standard SD tools for installation. If not, then nothing would be viewable in a 'swlist'.

Hi (again):

> I have tried #swverify as you mentioned,

But you don't say what if any errors you saw.

If there are errors you can try to fix them thusly:

# swverify -F \*

Too, do your LVM files have non-zero sizes or have they been corrupted? Do you have any filesystems that are full?

By the way, login directly as 'root' and perform the above.

It would appear that your system has serious problems.

The short excerpt you just posted indicates files that have been truncated to a 0 byte size.

You need to closely look at the swverify output and if there are lots of files that are of '0' size, then you may need to restore your system from a recent Ignite/UX backup.

Hi (again) Subodh:

> ERROR: File "/sbin/reboot" should have size "192512" bytes but the

This error (and others like it) is very bad. Without even opening your attached (non-text) file, I suspect that the sizes of your LVM executables are probably zero too. You should verify that with a simple 'ls /sbin/vg*' for example.

I suspect that some very catastrophic damage has been done.

I hope you have an Ignite recovery tape. Deploying that might be the fastest recovery method.

Hi,

I don't have ignite backup with me...

Is there any other solution like any patches (lvm, Co) which can fix this rather than going for cold installation,

Command patches like

PHCO_19479 1.0 LVM commands cumulative patch
PHCO_27369 1.0 LVM commands (VA7410 HWE) cumulative patch
PHCO_33244 1.0 LVM commands cumulative patch

Hi (again) Subodh:

> I don't have ignite backup with me...

But the real question is, do you even have one?

> Is there any other solution like any patches (lvm, Co) which can fix this rather than going for cold installation,

In the absence of an Ignite backup, if the damage is as widespread as it appears to be, a cold-install might be the faster route to a viable system. To try to reapply various products (base file sets) and their patches would probably be more time-consuming. You may then be struggling with problems for months.

"Is there any other solution like any patches...."

even if patches are out there, the contents of the filesystem appears to be corrupted already, so they wouldn't do you any good now.

note that a lot of the files appear to have been trunctated to 0, and within a relatively short period of time....

I believe you're going to have to cold install, then patch, or ignite.

"I don't have ignite backup with me..."

if one exists, and is recent, it may be worth the effort/expense/delay of getting it on-site. you'll have to make that determination however

Re: Not able to execute commands......

OldSchool — Fri, 19 Feb 2010 16:17:43 GMT

let me rephrase "even if patches are out there, the contents of the filesystem appears corrupted.."

and you've no garantee that patches will fix ALL the effected files.

>(a) Superuser(root) does not belong to group "sys".
>(3) This is output of my passwd file and group

Those files seem ok. What does id(1) show?

>(4) I have installed the sudo-1.7.2 utility
>make install ... it is not showing in the IPD.
>how I can remove it as I am not able to execute #swremove?

Of course, you must use swinstall for it to appear in the IPD and be able to use swremove.
You'll have to use rm to remove it. (Not sure why?)

>Is there any other solution like any patches which can fix this rather than going for cold installation,

Do you have another obsolete 11.00 system to copy those files?

Hi,once again..

As discussed, I have verified the error from

# Swverify -F \*

There was many files from /usr/sbin and /sbin like /VG/LV/PV/IO/boot/* was truncated to zero size due to which I was not able to execute all LVM/boot commands.

I able to restore all files of both dir from same version of server and fortunately yes, it works.

As we have donâ t have ignite backup, otherwise this could have been ended with cold installation of server.

Thanks you alwaysâ ¦ for your inputs!!!!!!! :)
