Hi Gurus,
I have production Server (E4500) attached with A1000 and i created two LUNS
with RM6.22 an put both the LUNS under Veritas Voulme Manager (3.3) with RAID
1. It was working fine from last month or so. Today i started getting emails
from VM saying that one disk (LUN) failed. When i checked the Luns everything
was fine but VM complains as NODEVICE. I ran healthchk and it shows optimal .I
also checked from RM GUI and it didn't gave any error either.Also format
command shows the disk (LUN) fine. But /var/adm/messages shows following
error:
Jul 16 11:16:39 sccpdb01 scsi: [ID 107833 kern.warning] WARNING:
/sbus@a,0/QLGC,isp@2,10000 (isp0):
Jul 16 11:16:39 sccpdb01 Parity Error
Follwing is output from Veritas:
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
c1t1d0s2 sliced - - online
- - oradata01 oradata1dg failed was:c1t1d0s2
i also checked prtdiag -v and is didn't reported any errors either.
What could be the probelm? Does that parity error on QLGC,isp2 indicate bad
controller? or bad disk? but if the disk is bad it should be reported by RM
and healthchk should report an error.
How do i make disk (LUN) under Veritas control again?
Please help
Thanks
BS
