IBM DS SAN Storage.
DS5020 mentions Enhanced Remote Mirror to multi-LUN applications
I wonder if Oracle High availibility can be setup using Remote Mirror option of SAN ?

Hi everyone,
I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?
At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)

rdc.cf
rdc.cf(4) File Formats rdc.cf(4)
NAME
rdc.cf - Availability Suite Remote Mirror software configuration file
DESCRIPTION
The rdc.cf is an optional configuration file that supplies the sndradm(1M) command with details of the volume sets to be operated on.
Inrdc.cf, the volume sets and their host locations are defined in the following format:
post pdevice pbitmap shost sdevice sbitmap protocol mode options
The rdc.cf fields are:
phost (primary host)
Server on which the primary volume resides.
pdevice (primary device)
Primary volume partition to be copied. Specify only full path names (for example, /dev/rdsk/c0t1d0s2).
pbitmap (primary bitmap)
Volume partition in which the bitmap (scoreboard logs) of the primary partition is stored. Specify only full path names (for exam-
ple, /dev/rdsk/c0t1d0s3).
shost (secondary host)
Server on which the secondary volume resides.
sdevice (secondary device)
Secondary volume partition. Specify only full path names (for example,/dev/rdsk/c0t1d0s4).
sbitmap (secondary bitmap)
Volume partition in which the bitmap (scoreboard logs) of the secondary file is stored. Specify only full path names (for example,
/dev/rdsk/c0t1d0s5).
protocol
Network transfer protocol. Specify IP.
mode
Remote Mirror operating mode. Sync is the Remote Mirror mode where the I/O operation is not confirmed as complete until the remote
volume has been updated. Async is the other Remote Mirror mode, in which the primary host I/O operation is confirmed as complete
before updating the remote volume.
options
A consistency group name can be specified using the g character. A disk queue volume partition can be specified using the q character,
using full path name only (/dev/rdsk/c0t1d0s5). Without the q character set will default to memory base queue. When running on
a clustered system, a cluster resource group tag can be specified using the C character.
These options have the following syntax:
[g io_groupname] [q queue_volume][C ctag]
Note -
When running on a cluster configuration, the cluster resource group tag is appended to the Remote Mirror set by default.
