system hangs on "Checking for crash dump"

V5.1B/Patch#4, DS10
System hangs on "Checking for crash dump" when boot up, what would possibly be the cause of
that?

Thanks,
Qing

Re: system hangs on "Checking for crash dump"

Hello
Can you give us more details? Are you able to boot the system in single user mode (without system crash)? Are you able to mount all file systems in single user mode? Try to "fsck" file systems (when in singe user mode).
Before going to next step you must be sure that everything is OK with your disks (hardware problem, i.e. bad blocks can also cause such a problem.

Re: system hangs on "Checking for crash dump"

I can boot in single user mode and mount all file systems. "/sbin/advfs/verify -a root_domain" as well as usr_domain also shows no problem. "init 3" on this point also
hangs up.

I did a "Ctrl-C" on "Checking crash dump", it bypassed but still crashed on a series
of stuff that follows.

Qing,

I'd say when in single-user mode, see what's in /var/adm/crash/. If there are files in there (besides bounds), move them somewhere else so the startup won't find them. Then try a reboot.

There's nothing in /var/adm/crash

Re: system hangs on "Checking for crash dump"

Hello
Is your "/var" file set in some domain or it is simbolic link to "/usr/var"?
I have another idea that maybe can help.
Try following:
1. Boot system in single user mode
2. Mount all file systems (do mount -a)
3. Manualy execute startup scripts in "/sbin/rc3.d" one by one
You will find out which script causes crash. Then we can analyze problem with more details.

Re: system hangs on "Checking for crash dump"

After the crash, reboot in single user mode (boot -fl s), then cd /sbin/init.d, then ls -ltu to see which file last accessed.
I have a similar case with advfsd daemon on a bad unmonted domain.

Re: system hangs on "Checking for crash dump"


The script that displays the "Checking for crash dumps" message is /sbin/init.d/savecore, called via the /sbin/rc2.d/S00savecore link.

Right after that message it executes "/sbin/savecore $DIR", where DIR is /var/adm/crash/ OR whatever you defined via SAVECORE_DIR in /etc/rc.config .

What happens when you execute:

sh -x /sbin/init.d/savecore ??

Hi Qing,

You need to install 5.B - Patch Kit5 to overcome this issue.

You can download the patch kit from

http://www1.itrc.hp.com/service/patch/patchDetail.do?patchid=T64KIT0023187-V51BB25-E-20040804

The ERP Kit name is T64KIT0023187-V51BB25-E-20040804.tar

Re: system hangs on "Checking for crash dump"


The ERP patchkit mentionned in previous post has no bearing at all on the issue at hand, and patchkit #5 is not out yet.

Furthermore T64KIT0023187-....-kit has been superseeded by T64KIT0024519-V51BB25-E-20041218 and corrects some UBC issues in addition to the panics with vm_pg_free and VPP_REPL...
