I am on Solaris 10 server which is running Veritas. It's E420 server with two drives. I don't know much about Veritas. The other guy who works on this, on vacation this week. :-) Any way, looks like I have hard drive issue on the server.
Code:
When I do iostat -E. I see this.

Veritas mirrors volumes residing on encapsulated disks, that are grouped in disk groups.
If those disks are part of a volume manager disk group, and have dynamic volume(s) on them, you could verify if the volume(s) are mirrored.
The following outputs indicate that my "ufs" volume, that is part of "testdg" disk gropup is mirrored across disks "hds9500-alua0_75" and "hds9500-alua0_77"
Disk "hds9500-alua0_83" holds the DRL log for fast mirror resync.
Question: When using Oracle Disk Manager with Veritas vxfs, what should be the proper setting for filesystem mount options (and file system io options), disk_async_io, convosync and DBWR processes?
Answer: Every system has different optimizations, but here are some guidelines for optimizing Veritas vxfs on Oracle. The Veritas Cluster Server, supporting Oracle RAC, is pretty much an extended and enhanced version of the VCS used for database failover clusters. Veritas DBE/AC is a certified cluster framework that is built in with Cluster File System and it is ODM compliant.
Set direct I/O for Veritas: convosync=direct. It is also possible to enable direct I/O on a per-file basis using Veritas QIO; refer to the "qiostat" command and corresponding man page for hints.
Oracle’s DBWR now writes continuously without waiting for previous writes to complete. The new design allows DBWR to act as if it were inherently synchronous, regardless of whether the operating system supports asynchronous I/O or not.
To determine whether to use multiple DBWn processes or database slaves, follow these guidelines:
Use db_writer_processes for most write intensive applications. One per CPU is the recommended setting.
Use db_writer_processes for databases that have a large data buffer cache.
Use dbwr_io_slaves for applications that are not write intensive and run on operating systems that support asynchronous I/O.
Use dbwr_io_slaves on platforms that do no support asynchronous I/O.
Use dbwr_io_slaves on single CPU systems. Multiple DBWR processes are CPU intensive.
Hi all
I have a DLT tape in that tape backup is there is in veritas volume format and i want to restore it in ufs file system how can i do it?
right now i don't have veritas file system setup. i have only ufs file sysytem

Hi all, I'm fairly new to Veritas on Linux machines and have a disk group with 64 disks that we are migrating to 64 new disks. This means I'll be mirroring the old to the new. So my question is this - is there a way to mirror a specific volume to a range of disks as opposed to listing each disk by... (0 Replies)
Dear All,

hi every one ,

but i m facing problem in veritas file system .
i wants to know how will i create swap or add new swap space in existing swap space .
Note: disk under veritas volume manager control .
please help me to solve this issue . (5 Replies)
Can someone tell me what command it is to list the disk in a specified disk group. I dont want to see disks in all groups, just the disk in a specified group. (2 Replies)
vxdg -g mktdg adddisk mktdg02=c0b0t3d0
i know this command adds c0b0t3d0 to the disk group mktdg but what i dont know is what the significance of mktdg02 is.
i mean, what is it? what does it stand for?? (1 Reply)

Hello All. I have a question concerning VFS (Veritas File System).
I are attempting to upgrade Solaris 2.6 UFS to the VFS (Veritas File System). We use Veritas to perform all our backups. I have been unable to find any documentation on SUN's or Veritas's website. The server's are SUN 4500 and... (3 Replies)
