Informix in MCSG

[yc_2]

Hi,

Has anyone encountered the when 1 node shutdown (2 nodes cluster using EVA3000 with mirroring of LVM in both nodes for HA), informix will give the following?

3:35:48 I/O read chunk 148, pagenum 2, pagecnt 1 --> errno = 4
13:35:48 I/O read chunk 153, pagenum 2, pagecnt 1 --> errno = 4

both chunks are marked "DOWN" in the onstat -d output.

c00000000b02f028 153 31 750000 200000 0 PD-- /dev/admprod7/
c00000000b046ce8 153 31 750000 200000 0 MD-- /dev/admmirror7/

Informix said the problem is due to the disk but when contacted HP they said no problem with the disk.

Thanks in advance for any advice.

What do you mean by "mirroring of LVM in both nodes for HA". HA in the array is provided by the RAID function of the array.
