Synchronous I/O error while paging to/from disk

Hey;

 

Different system this time, in case anyone's following the other thread...  

 

An rx2620, up for 42 days, is regularly reporting:

 

Nov 17 00:43:59 mars vmunix: Synchronous Page I/O error occurred while paging to/from disk
Nov 17 00:43:59 mars vmunix: device 0x4001000a, 1K block #2408760, 65536 bytes of 65536 bytes not paged, page addr =dead31.e000000300810000,
bflag =40008f, bp = e00000031fbf6700

 

All disks are showing up claimed.  In fact, all h/w is showing claimed as evidenced by "ioscan -f".  The only squirrelly disk configuration is the use of one legacy device:

 

# strings /etc/lvmtab
/dev/vg01
/dev/dsk/c2t0d0
/dev/disk/disk5
/dev/vg00
/dev/disk/disk6_p2
/dev/vg02
/dev/disk/disk14

 

That, however, translates to disk4 which isn't used anywhere else.

 

I can't seem to figure out how to translate the device hex number into a device name.  Can anyone let me know how to do that?

 

Thanks.
