41. 41 Student Guide:

42. 42 Interfaces to OLAR System Administration Manager, SAM –Graphical user interface (GUI) –The primary interface rad –Command line interface –Developed for single-user mode when SAM not yet available –Not generally recommended

43. 43 Student Guide:

44. 44 Planning and Preparation Issues Slot compatibility Driver compatibility Impact on the system –To the OS –To SAM –To other applications

45. 45 Student Guide:

46. 46 Considerations for Critical Resources Critical resource: a resource that, if lost, would cause the system to crash, or the OLA/R operation to fail Examples: –Swap partition –/, /usr, /etc, and /var filesystems –Network card carrying connection for SAM displayed on a remote machine

47. 47 Student Guide:

48. 48 Considerations for Power Domains Does not affect SuperDome Every slot is an individual power domain Other Systems Power domain: A grouping of 2 or more interface card slots that are powered on or off as a unit. In many cases, there exist dependencies between other interface cards, slots, and power domains within the system.

49. 49 Student Guide:

50. 50 Considerations for Multi-Function I/O Cards All functions on the same power source Must suspend all functions to remove the card Must resume all functions to bring the card back Must account for multiple affected cards in the critical resource analysis

51. 51 Student Guide:

52. 52 Failover Failover means that the system will use an alternate resource if the primary resource is unavailable Critical resource analysis will prevent suspension of resources that do not have an alternate The system may operate with a single point of failure for a short time

53. 53

54. 54 Online Card Replacement Replacement card must be identical type of card Must use same driver Must have same number of functions or ports Must have compatible power and frequency requirements Single point of failure may result when card is suspended and its backup takes over

55. 55 Student Guide:

56. 56 Card Replacement with SAM Start SAM Select Peripheral Devices --> Cards From the Sys Admin view of active I/O adapters, choose the adapter to be replaced Select PCI slot, then Replace action –SAM analyzes critical resources Physically remove old card and insert new card SAM finishes replacement by restarting card
