Troubleshooting
Problem
PC Servers with a disk partition of 17GB or larger may receive an insufficient memory error while running CHKDSK, or CHKDSK may fail to complete (hang) when run on a large disk partition. The system may hang with only a partial error message displayed onthe monitor. For example, the error message "HFS #####" may be displayed as "H" due to the hang.
Resolving The Problem
Abstract :
Insufficient Memory Error with CHKDSK
Symptom :
PC Servers with a disk partition of 17GB or larger may receive an insufficient memory error while running CHKDSK.
-OR-
CHKDSK may fail to complete (hang) when run on a large disk partition. The system may hang with only a partial error message displayed on the monitor. For example, the error message "HFS #####" may be displayed as "H" due to the hang.
Problem Isolation Aids :
- The system is a PC Server with an IBM RAID adapter.
- The Operating System is OS/2 2.11, 2.11 SMP, 3.0, 4.0 or Warp Server.
- CHKDSK is run on a disk partition of 17GB or larger.
Fix :
Do not replace any hardware; this is a software error.
Note: CHKDSK runs for a long time on large partitions; it is NOT unusual for CHKDSK to run for 90 minutes or longer on a 17GB partition. CHKDSK may still be running even though it appears to be hung, so allow enough time for it to complete.
Follow this procedure as a work-around:
1. Make a backup of the CONFIG.SYS file.
2. Edit the CONFIG.SYS file and remove the drive letter causing the error/hang from the AUTOCHECK parameter in the IFS (Install File System) statement.
IFS=C: OS2 HPFS.IFS /CACHE:1024 /CRECL:64 /AUTOCHECK:CD <--drive letter
3. Restore data from a current backup.
For additional information refer to OS/2 defect 155730 and/or APAR PJ18004.
