Actual Failover At The Recovery Site; Troubleshooting The Hp Storageworks P4000 Sra - HP StorageWorks P4000 User Manual

Actual failover at the recovery site

In the event of a disaster, the SRM can perform actual failover when requested to. When actual failover
is requested the HP StorageWorks P4000 SRA will perform the steps listed.
1. Select the replicated volumes.
2. Identify and remove any incomplete remote copies that are in progress and present the most
recent completed Remote Copy as a primary volume.
3. Convert remote volumes into primary volumes and configure authentication for ESX servers to
mount them
If an actual failover does not run completely for any reason, the failover can be called many times to
try to complete the run. If, for example, only one volume failed to restore and that was due to a normal
snapshot being present, the snapshot could be manually deleted and the failover be requested again.

Troubleshooting the HP StorageWorks P4000 SRA

Table 1 Troubleshooting the HP StorageWorks P4000 SRA
Problem
The HP StorageWorks P4000
SAN array does not appear
in the drop down list of arrays
for SRM.
SRM does not see the volumes
that are replicated.
CHAP-authenticated ESX serv-
ers are failing to perform test
failovers or actual failover.
The HP StorageWorks P4000
SRA fails to connect to the
SAN.
When the HP StorageWorks
P4000 SAN array is dis-
covered, an error message
states there are duplicate
LUNs.
10 Using the HP StorageWorks P4000 SRA for VMware SRM
Cause
The HP StorageWorks P4000 SRA might
not be installed or the SRM service has
not restarted since the HP StorageWorks
P4000 SRA was installed.
Volumes are only reported as replicated
to SRM if they have a Remote Copy
schedule.
SRM does not store or pass CHAP pass-
words to the HP StorageWorks P4000
SRA. For CHAP authentication to work,
the authentication group with correct
password must be already configured
on the SAN/iQ management group.
SRM servers running the HP Storage-
Works P4000 SRA must be able to route
TCP/IP traffic to the SAN that is to be
managed and must have a valid user-
name and password.
Both the primary and remote volume
might be mounted at the same site.
Solution
Install the HP StorageWorks P4000
SRA and restart the VMware Site
Recovery Manager Service.
Create a Remote Copy schedule
for all volumes that are to be man-
aged by SRM.
Create authentication groups for
any CHAP authentication required
on the recovery site before running
test failover or failover.
Configure a network that can route
from SRM servers to the HP Stor-
ageWorks P4000 SAN Solution,
and verify the user account con-
figured in SRM.
Do not mount primary and remote
volumes at the same site at the
same time.
