Disk Crash

Angela L. Shepherd_1 — Mon, 09 Apr 2001 18:39:16 GMT

I had 2 yellow lights on one of my disk units. I rebooted the machine and the lights went away. I ran an arrayscan and tried to display the disk using the ./dsp -l /dev/rdsk/c0t0d0 command under /usr/hpC2400/bin but I keep receiving the following error message:

dsp: initdev - internal error: Can't locate device mapping file. Run "arrayscan". What am I doing wrong or is it an easier way to make sure my disk are OK.

Angela,

I would say if you can do the following on the disk in question, it's ok:

1) diskinfo -v /dev/rdsk/c?t?d?
2) pvdisplay -v /dev/dsk/c?t?d?
3) vgdisplay on the vg that the disk belongs to.

If all of these come back without errors, you're probably ok - otherwise you may have a hardware problem.

Angela, their are old sys admins and bold sys admins, but there are no old, bold sys admins.

With all due respect for my colleague if you have an HP support contract then it is time to let HP earn their money.

If not, then you have to decide if it is worth the money to call them out based on your perceptions.

Angela,

here's some more info:

When going into Disks and Filesystems they get the error:

"The command used to retrieve disk array configuration data,
/usr/sam/lbin/get_array_info, has encountered an error. The stderr
output from the command is shown below. Until the problem mentioned
below is fixed, SAM cannot recognize the array's configuration.

arrayinfo: initdev - internal error: Can't locate device mapping
file. Run "arrayscan".
dsp: initdev - internal error: Can't locate device mapping file. Run
"arrayscan".
arrayinfo: initdev - internal error: Can't locate device mapping
file. Run "arrayscan".
dsp: initdev - internal error: Can't locate device mapping file. Run
"arrayscan".
arrayinfo: initdev - internal error: Can't locate device mapping
file. Run "arrayscan".
dsp: initdev - internal error: Can't locate device mapping file."

Cause Text

pd_devinfo.tx, was delivered with bogus entries for EMC that
were not there in PHCO_11361. This was a mistake. Because
of this the code believes that the EMC is a SCSI CASCADE
array and treats it as such (ie. calls get_array-info).

Fix Text

remove the EMC lines from pd/data/pd_devinfo.tx
