pvlinks - pvchange

[Garry Taylor_3]

After I set my pvlinks "pvchange -t 180 /dev/rdsk/cXtYdZ" and later down the line after a reboot or shutdown will the time value revert back to the default?
Can any one tell me what the default time is? pvdisplay just shows default.

not sure what the default time is but if you wan to make it permanent consider using vgchange to make the permanent

Hi Garry,

I believe the default value is normally 30 seconds. But if someone runs pvchange -t 0 then the default will be the value supplied by the device - which can vary.
Also remember that lvchange can set an I/O timeout as well & if it's shorter then it will trigger the I/O error.
If lvchange -t 0 is run then it will wait "forever" - i.e. never timeout.
And yes, once set they stay until overriden with the next lv/pvchange -t command.

HTH,
Jeff

Hi Garry,

what OS you are using?

BTW, remove the **r** (rdsk) from the command

pvchange -t 180 /dev/dsk/cXtYdZ

Hi Garry,

pvchnage value will not chage from the set value after reboot.

We used to set to 180 seconds for the clarrion devices as recommended by EMC.


Default time I am not sure , guess it is 60


Thanks.

Thanks to all, Receiving a lot of AVT's and I had to ensure the timeout value was set to 180 (STK/SUN) disk array. I wasnt sure about the change of value being pernament on a reboot.
