SLES8 + DL380G3 + sar / iostat

[eduardo_41]

Hi all,

We're using SuSE Linux Enterprise 8 + SP3 + PSP 7.10 + DL 380 G3 .

When I type 'sar -d' I get: "Requested activities not available in file"

I've checked /usr/src/linux/.config and it have 'CONFIG_BLK_STATS=y'.

To make sure, I've recompiled the kernel, copied it to /boot and rebooted, but no success.

I've tried installing SLES8+SP3 on a new PC (with IDE disks) and I got the sar counters... the "problem" is only with proliant servers...

Any clye?

Thanks,
Eduardo

I doubt this is an issue limited to proliant servers.

I would think it would relate more to configuration and or kernel differences between the servers where the sar command work and the proliant servers.

Could be an issue with recognizing disk thats hung off fibre.

Hi, thanks for reply.

All disks are Ultra320 on Smart 5i (on server box), it's not a external storage.

I've tried a new install:
- SLES8 with default settings / reboot
- SLES8SP3 with all updates / reboot

And then:
---
host:/usr/src/linux # sar -d
Linux 2.4.19-64GB-SMP (sv10) 07/20/04

11:50:00 DEV tps blks/s
---

No values, even if I do a "massive copy of some GB files".

Another strange thing is why sar says "Linux 2.4.19" if uname -a gives "Linux 2.4.21-138-smp" ?

Thanks,
Eduardo
