SCSI controller issue.
A message that is not in the archive (sent off-list or not yet received): [email protected]
Afternoon,
I am using PERC 4/D scsi controller card for out Power Vault + RHEL AS 2.1 fro cluster.
1. I got lots of I/O error on filesystem( ext3 ), while using Power Vault 220s with PERC 3/D scsi controller card.
2. After chaning it to PERC 4/D card am facing following issuse:
It does not allow me to make more then one LUN on the Power Vault. If I have 4 disk in R5 and one HS configured on PV 220s. ( in case
if any disk of R5 fails ) then second node gets different status about the disk status. i.e on Primary node it shows HS getting in to rebuild status & over node 2 it gives status of DISK FAIL.)
3. We changed the PERC 3/D to PERC 4/D 'cause of listed reasons:
It supports 160mpbs, where as PERC 4/D supports 320 mpbs ( which
is the same speed provided by PV Controller.
SCSI cables from nodes to PV were 10feets long, so we went for
shorter cable.
The issue is that if I take up server live then in case of R5 disk failure + Primary node failure ( on which service at that time will run ), then in this case will my secondary node takes up the service and rebuild the R5 or not?
And the flexbility of having more then one LUN on PERC 3/D is not support on PERC 4/D SCSI controller card.
Regards,
Animesh.
