Steps
I have a few customers and IBMers tell me their Shared Storage Pool (SSP) failed to come up after some major disaster like
- Total network outage
- Total SAN outage
- Total site unexpected electrical power outage
They then fiddle about and eventually, like hours or even days later, send me email.
All I can say is I am sorry to hear about their issue, that I don't have that problems and I have had my share of electricity cuts (ironically while testing the uninterruptible power supply!). But I can offer some advice . . .
- Prepare to send IBM Support diagnostic data about the SSP and even create a SSP snap in advance: clffdc (for example: clffdc -c FULL -p 2) then be prepared to send them large file it creates.
- Pro-actively do your part. Be prepared to answer questions quickly and follow instructions to minimise the down time.
From working with the VIOS Shared Storage Pool support and development team, I am always impressed with their diagnosis skills and ability to workout a trick problem.
