Setting the I/O timeout parameter

Set the I/O timeout value for each disk device to 30 seconds.

To change the I/O timeout parameter:

1. Verify the current I/O timeout value using the pvdisplay command:

Example

# pvdisplay /dev/dsk/c0t6d0

This causes current values to be displayed:

--- Physical volumes ---

PV Name /dev/dsk/c0t6d0

VG Name /dev/vg06

PV Status available

Allocatable yes

VGDA 2

Cur LV 1

PE Size (Mbytes) 4

Total PE 586

Free PE 0

Allocated PE 586 [OPEN-9]

Stale PE 0

IO Timeout (Seconds) default [I/O timeout value]

2. If the I/O timeout value is not 30, change the value to 30 using the

pvchange -t command:

Example

# pvchange -t 30 /dev/dsk/c0t6d0

This result is displayed:

Physical volume "/dev/dsk/c0t6d0" has been

successfully changed.

Volume Group configuration for /dev/vg06 has been

saved in /etc/lvmconf/vg06.cof

3. Verify that the new I/O timeout value is 30 seconds using the pvdisplay

command:

Example

# pvdisplay /dev/dsk/c0t6d0

Current values are now displayed, confirming that the new I/O timeout

value is 30 seconds:

1 2 ... 42 43 44 45 46 47 48 49 50 51 52 ... 81 82
